This change will remove the notion of types completely from the Search API internals.

For classes that are serialised (such as SearchRequest, IdsQuery, ShardLocalSearchRequest) we need to check for the wire version and deal with the types serialisation if the other node is <8.0.0

@jpountz I was hoping this would be easier to split into incremental changes. All I managed to do was split the changes from removing types from SearchRequest into a separate commit to the ones removing types from QueryShardContext. I can split the commits into 2 separate PRs if you prefer? Also open to thoughts on better ways to split this if think it needs to be made smaller?

It looks good overall. I think we should fail deserialization of request builders when the set of types is not empty? My worry is that we might hide bugs otherwise, eg. if a user is querying a different type than the type of the index: if we ignore types, the query might match some documents while it shouldn't?

Add debug log for retention leases (#42557)

We need more information to understand why CcrRetentionLeaseIT is
failing. This commit adds some debug log to retention leases and enables
them in CcrRetentionLeaseIT.

Improve how internal representation of pipelines are updated (#42257)

If a single pipeline is updated then the internal representation of
all pipelines was updated. With this change, only the internal representation
of the pipelines that have been modified will be updated.

Prior to this change the IngestMetadata of the previous and current cluster
was used to determine whether the internal representation of pipelines
should be updated. If applying the previous cluster state change failed then
subsequent cluster state changes that have no changes to IngestMetadata
will not attempt to update the internal representation of the pipelines.

This commit, changes how the IngestService updates the internal representation
by keeping track of the underlying configuration and use that to detect
against the new IngestMetadata whether a pipeline configuration has been
changed and if so, then the internal pipeline representation will be updated.

Reset state recovery after successful recovery (#42576)

The problem this commit addresses is that state recovery is not reset on a node that then becomes
master with a cluster state that has a state not recovered flag in it. The situation that was observed
in a failed test run of MinimumMasterNodesIT.testThreeNodesNoMasterBlock (see below) is that we
have 3 master nodes (node_t0, node_t1, node_t2), two of them are shut down (node_t2 remains),
when the first one comes back (renamed to node_t4) it becomes leader in term 2 and sends state
(with state_not_recovered_block) to node_t2, which accepts. node_t2 becomes leader in term 3, and
as it was previously leader in term1 and successfully completed state recovery, does never retry
state recovery in term 3.

Lazily compute Java 8 home in reindex configuration (#42630)

In the reindex from old tests we require Java 8. Today when configuring
the reindex from old tests, we eagerly evalulate Java 8 home, which
means that we require JAVA8_HOME to be set even if the reindex from old
test tasks are not in the task graph. This is an onerous requirement if,
for example, all that you want to do is build a distribution. This
commit addresses this by making evaluation of Java 8 home lazy, so that
it is only done and required if the reindex from old test tasks would be
executed.

Remove "nodes/0" folder prefix from data path (#42489)

With the removal of node.max_local_storage_nodes, there is no need anymore to keep the data in
subfolders indexed by a node ordinal. This commit makes it so that ES 8.0 will store data directly in
$DATA_DIR instead of $DATA_DIR/nodes/$nodeOrdinal.

Upon startup, Elasticsearch will check to see if there is data in the old location, and automatically
move it to the new location. This automatic migration only works if $nodeOrdinal is 0, i.e., multiple
node instances have not previously run on the same data path, which required for
node.max_local_storage_nodes to explicitly be configured.

Refactor HLRC RequestConverters parameters to be more explicit (#42128)

The existing `RequestConverters.Params` is confusing, because it wraps
an underlying request object and mutations of the `Params` object
actually mutate the `Request` that was used in the construction of the
`Params`.

This leads to a situation where we create a `RequestConverter.Params`
object, mutate it, and then it appears nothing happens to it - it
appears to be unused. What happens behind the scenes is that the Request
object is mutated when methods on `Params` are invoked. This results in
unclear, confusing code where mutating one object changes another with
no obvious connection.

This commit refactors `RequestConverters.Params` to be a simple helper
class to produce a `Map` which must be passed explicitly to a Request
object. This makes it apparent that the `Params` are actually used, and
that they have an effect on the `request` object explicit and easier to
understand.

Propogate version in reindex from remote search (#42412)

This is related to #31908. In order to use the external version in a
reindex from remote request, the search request must be configured to
request the version (as it is not returned by default). This commit
modifies the search request to request the version. Additionally, it
modifies our current reindex from remote tests to randomly use the
external version_type.

Detect when security index is closed (#42191)

If the security index is closed, it should be treated as unavailable
for security purposes.

Prior to 8.0 (or in a mixed cluster) a closed security index has
no routing data, which would cause a NPE in the cluster change
handler, and the index state would not be updated correctly.
This commit fixese that problem

Fix testTokenExpiry flaky test (#42585)

Test was using ClockMock#rewind passing the amount of nanoseconds
in order to "strip" nanos from the time value. This was intentional
as the expiration time of the UserToken doesn't have nanosecond
precision.
However, ClockMock#rewind doesn't support nanos either, so when it's
called with a TimeValue, it rewinds the clock by the TimeValue's
millis instead. This was causing the clock to go enough millis
before token expiration time and the test was passing. Once every
few hundred times though, the TimeValue by which we attempted to
rewind the clock only had nanos and no millis, so rewind moved the
clock back just a few millis, but still after expiration time.

This change moves the clock explicitly to the same instant as expiration,
using clock.setTime and disregarding nanos.

Log leader and handshake failures by default (#42342)

Today the `LeaderChecker` and `HandshakingTransportAddressConnector` do not log
anything above `DEBUG` level. However there are some situations where it is
appropriate for them to log at a higher level:

- if the low-level handshake succeeds but the high-level one fails then this
  indicates a config error that the user should resolve, and the exception
  will help them to do so.

- if leader checks fail repeatedly then we restart discovery, and the exception
  will help to determine what went wrong.

Fix refresh remote JWKS logic (#42662)

This change ensures that:

- We only attempt to refresh the remote JWKS when there is a
signature related error only ( BadJWSException instead of the
geric BadJOSEException )
- We do call OpenIDConnectAuthenticator#getUserClaims upon
successful refresh.
- We test this in OpenIdConnectAuthenticatorTests.

Without this fix, when using the OpenID Connect realm with a remote
JWKSet configured in `op.jwks_path`, the refresh would be triggered
for most configuration errors ( i.e. wrong value for `op.issuer` )
and the kibana wouldn't get a response and timeout since
`getUserClaims` wouldn't be called because
`ReloadableJWKSource#reloadAsync` wouldn't call `onResponse` on the
future.

Prevent merging nodes' data paths (#42665)

Today Elasticsearch does not prevent you from reconfiguring a node's
`path.data` to point to data paths that previously belonged to more than one
node. There's no good reason to be able to do this, and the consequences can be
quietly disastrous. Furthermore, #42489 might result in a user trying to split
up a previously-shared collection of data paths by hand and there's definitely
scope for mixing the paths up across nodes when doing this.

This change adds a check during startup to ensure that each data path belongs
to the same node.

Clarify the settings around limiting nested mappings. (#42686)

* Previously, we mentioned multiple times that each nested object was indexed as its own document. This is repetitive, and is also a bit confusing in the context of `index.mapping.nested_fields.limit`, as that applies to the number of distinct `nested` types in the mappings, not the number of nested objects. We now just describe the issue once at the beginning of the section, to illustrate why `nested` types can be expensive.
* Reference the ongoing example to clarify the meaning of the two settings.

Remove SecurityClient from x-pack (#42471)

This commit removes the SecurityClient class from x-pack. This client

client and others use a client directly without the security client
wrapping it.

Remove Log4j 1.2 API as a dependency (#42702)

We had this as a dependency for legacy dependencies that still needed
the Log4j 1.2 API. This appears to no longer be necessary, so this
commit removes this artifact as a dependency.

To remove this dependency, we had to fix a few places where we were
accidentally relying on Log4j 1.2 instead of Log4j 2 (easy to do, since
both APIs were on the compile-time classpath).

Finally, we can remove our custom Netty logger factory. This was needed
when we were on Log4j 1.2 and handled logging in our own unique
way. When we migrated to Log4j 2 we could have dropped this
dependency. However, even then Netty would still pick up Log4j 1.2 since
it was on the classpath, thus the advantage to removing this as a
dependency now.

Remove client jar support from build (#42640)

Add option to ObjectParser to consume unknown fields (#42491)

ObjectParser has two ways of dealing with unknown fields: ignore them entirely,
or throw an error. Sometimes it can be useful instead to gather up these unknown
fields and record them separately, for example as arbitrary entries in a map.

This commit adds the ability to specify an unknown field consumer on an ObjectParser,
called with the field name and parsed value of each unknown field encountered during
parsing. The public API of ObjectParser is largely unchanged, with a single new
constructor method and interface definition.

address SmokeTestWatcherWithSecurityIT#testSearchInputWithInsufficientPrivileges (#42764)

This commit adds busy wait and increases the interval for
SmokeTestWatcherWithSecurityIT#testSearchInputWithInsufficientPrivileges.

Watcher will not allow the same watch to be executed concurrently. If it
finds that case, it will update the watch history with a "not_executed_already_queued"
status. Given a slow machine, and 1 second interval this is possible.

To address this, this commit increases the interval so the watch can fire at most 2
times with a greater interval between the executions and adds a busy wait for the
expected state.

While this does not gaurntee a fix, it should greatly reduce the chances of this
test erroring.

[ML] Better detection of binary input in find_file_structure (#42707)

This change helps to prevent the situation where a binary

detected as being text in the UTF-16 character set, and
then causes a large amount of CPU to be spent analysing
the bogus text structure.

The approach is to check the distribution of zero bytes
between odd and even file positions, on the grounds that
UTF-16BE or UTF16-LE would have a very skewed distribution.

[ML] Add a limit on line merging in find_file_structure (#42501)

When analysing a semi-structured text file the
find_file_structure endpoint merges lines to form
multi-line messages using the assumption that the
first line in each message contains the timestamp.
However, if the timestamp is misdetected then this
can lead to excessive numbers of lines being merged
to form massive messages.

This commit adds a line_merge_size_limit setting
(default 10000 characters) that halts the analysis
if a message bigger than this is created.  This
prevents significant CPU time being spent subsequently
trying to determine the internal structure of the

Read the default pipeline for bulk upsert through an alias (#41963)

This commit allows bulk upserts to correctly read the default pipeline
for the concrete index that belongs to an alias.

Bulk upserts are modeled differently from normal index requests such that
the index request is a request inside of the update request. The update
request (outer) contains the index or alias name is not part of the (inner)
index request. This commit adds a secondary check against the update request
(outer) if the index request (inner) does not find an alias.

More improvements to cluster coordination docs (#42799)

This commit addresses a few more frequently-asked questions:

* clarifies that bootstrapping doesn't happen even after a full cluster

* removes the example that uses IP addresses, to try and further encourage the
  use of node names for bootstrapping.

* clarifies that auto-bootstrapping might form different clusters on different
  hosts, and gives a process for starting again if this wasn't what you wanted.

* adds the "do not stop half-or-more of the master-eligible nodes" slogan that
  was notably absent.

* reformats one of the console examples to a narrower width

Make high level rest client a fat jar (#42771)

The original intention of the high level rest client was to provide a
single jar. We tried this long ago, but had issues with intellij not
correctly resolving internal tests that relied on the HLRC. This
commit tweaks our use of the shadow plugin so we now produce a correct
fat jar (minus the LLRC and server jars, which we can address later),
with the module "client" dependencies included, as well as the
correct pom file omitting those dependencies.

Don't require TLS for single node clusters (#42826)

This commit removes the TLS cluster join validator.

This validator existed to prevent v6.x nodes (which mandated
TLS) from joining an existing cluster of v5.x nodes (which did
not mandate TLS) unless the 6.x node (and by implication the
5.x nodes) was configured to use TLS.

Since 7.x nodes cannot talk to 5.x nodes, this validator is no longer
needed.

Removing the validator solves a problem where single node clusters
that were bound to local interfaces were incorrectly requiring TLS
when they recovered cluster state and joined their own cluster.

OIDC Guide additions (#42555)

Fix version parsing in various tests (#42871)

This commit fixes the version parsing in various tests. The issue here is that
the parsing was relying on java.version. However, java.version can contain
additional characters such as -ea for early access builds. See JEP 233:

Name                            Syntax
------------------------------  --------------
java.version                    $VNUM(\-$PRE)?
java.runtime.version            $VSTR
java.vm.version                 $VSTR
java.specification.version      $VNUM
java.vm.specification.version   $VNUM

Instead, we want java.specification.version.

Deduplicate alias and concrete fields in query field expansion (#42328)

The full-text query parsers accept field pattern that are expanded using the mapping.
Alias field are also detected during the expansion but they are not deduplicated with the
concrete fields that are found from other patterns (or the same). This change ensures
that we deduplicate the target fields of the full-text query parsers in order to avoid
adding the same clause multiple times. Boolean queries are already able to deduplicate
clauses during rewrite but since we also use DisjunctionMaxQuery it is preferable to detect
 these duplicates early on.

This PR changes dots into underscores in CSV field names

the field names are specifically overridden.  The reason for
allowing them in overrides is that fields that are not
mentioned in the ingest pipeline can contain dots.  But it's
more consistent that the default behaviour is to replace
them all.

Improve translog corruption detection (#42744)

However, we rely on _all_ corruptions leading to this exception in the
`RemoveCorruptedShardDataCommand`: this command fails if a translog file
corruption leads to a different kind of exception, and `EOFException` and
`NegativeArraySizeException` are both possible. This commit strengthens the
translog corruption detection tests by simulating the following:

- a bit is flipped
- all bits are cleared or set
- a random value is written
- the file is truncated

It also makes sure that we return a `TranslogCorruptionException` in all such
cases.

Fix possible NPE in put mapping validators (#43000)

When applying put mapping validators, we apply all the validators in the
collection. If a failure occurs, we collect that as a top-level
exception, and suppress any additional failures into the top-level
exception. However, if a request passes the validator after a top-level
exception has been collected, we would try to suppress a null exception
into the top-level exception. This is a violation of the
Throwable#addSuppressed API. This commit addresses this, and adds test
to cover the logic of collecting the failures when validating a put
mapping request.

Fix IOUtils#fsync on Windows fsyncing directories (#43008)

Fsyncing directories on Windows is not possible. We always suppressed
this by allowing that an AccessDeniedException is thrown when attemping
to open the directory for reading. Yet, this suppression also allowed
other IOExceptions to be suppressed, and that was a bug (e.g., the
directory not existing, or a filesystem error and reasons that we might
get an access denied there, like genuine permissions issues). This
leniency was previously removed yet it exposed that we were suppressing
this case on Windows. Rather than relying on exceptions for flow control
and continuing to suppress there, we simply return early if attempting
to fsync a directory on Windows (we will not put this burden on the
caller).

Allow routing commands with ?retry_failed=true (#42658)

We respect allocation deciders, including the `MaxRetryAllocationDecider`, when
executing reroute commands. If you specify `?retry_failed=true` then the retry
counter is reset, but today this does not happen until after trying to execute
the reroute commands. This means that if an allocation has repeatedly failed,
but you want to take control and assign a shard to a particular node to work
around the repeated failures, you cannot execute the routing command in the
same call to `POST /_cluster/reroute` as the one that resets the failure
counter.

This commit fixes this by resetting the failure counter first, meaning that you
can now explicitly allocate a repeatedly-failed shard like this:

```
POST /_cluster/reroute?retry_failed=true
{
  "commands": [
    {
      "allocate_replica": {
        "index": "blahblah",
        "shard": 2,
        "node": "node-4"
      }

[ML] Re-enable integration test (#41712)

Move construction of custom analyzers into AnalysisRegistry (#42940)

Both TransportAnalyzeAction and CategorizationAnalyzer have logic to build
custom analyzers for index-independent analysis. A lot of this code is duplicated,
and it requires the AnalysisRegistry to expose a number of internal provider
classes, as well as making some assumptions about when analysis components are
constructed.

This commit moves the build logic directly into AnalysisRegistry, reducing the
registry's API surface considerably.

Clean up configuration when docker isn't available (#42745)

We initially added `requireDocker` for a way for tasks to say that they
absolutely must have it, like the  build docker image tasks.
Projects using the test fixtures plugin are not in this both, as the
intent with these is that they will be skipped if docker and docker-compose
is not available.

Before this change we were lenient, the docker image build would succeed
but produce nothing. The implementation was also confusing as it was not
immediately obvious this was the case due to all the indirection in the
code.

The reason we have this leniency is that when we added the docker image
build, docker was a fairly new requirement for us, and we didn't have
it deployed in CI widely enough nor had CI configured to prefer workers
with docker when possible. We are in a much better position now.
The other reason was other stack teams running `./gradlew assemble`
in their respective CI and the possibility of breaking them if docker is
not installed. We have been advocating for building specific distros for
some time now and I will also send out an additional notice

The PR also removes the use of `requireDocker` from tests that actually
use test fixtures and are ok without it, and fixes a bug in test
fixtures that would cause incorrect configuration and allow some tasks
to run when docker was not available and they shouldn't have.

[DOCS] Change `// TESTRESPONSE[_cat]` to `// TESTRESPONSE[non_json]` (#43006)

[ML] Get resources action should be lenient when sort field is unmapped (#42991)

Get resources action sorts on the resource id. When there are no resources at
all, then it is possible the index does not contain a mapping for the resource
id field. In that case, the search api fails by default.

This commit adjusts the search request to ignore unmapped fields.

Increase waiting time when check retention locks (#42994)

WriteActionsTests#testBulk and WriteActionsTests#testIndex sometimes
fail with a pending retention lock. We might leak retention locks when
switching to async recovery. However, it's more likely that ongoing
recoveries prevent the retention lock from releasing.

This change increases the waiting time when we check for no pending
retention lock and also ensures no ongoing recovery in
WriteActionsTests.

Closes #41054

Rename processor test fix (#43035)

If the source field name is a prefix of the target field name, the
source field still exists after rename processor has run. Adjusted test
case to handle that case.

Default distro run creates elastic-admin user (#43004)

When using gradle run by itself, this uses the default distro with a
basic license and enables security. There is a setup command to create
a elastic-admin user but only when the license is a trial license. Now
that security is available with the basic license, we should always run
this command when using the default distribution.

Better test diag output on OOM (#42989)

If linearizability checking fails with OOM (or other exception), we did
not get the serialized history written into the log, making it difficult
to debug in cases where the problem is hard to reproduce. Fixed to
always attempt dumping the serialized history.

Refresh remote JWKs on all errors (#42850)

It turns out that key rotation on the OP, can manifest as both
a BadJWSException and a BadJOSEException in nimbus-jose-jwt. As
such we cannot depend on matching only BadJWSExceptions to
determine if we should poll the remote JWKs for an update.

This has the side-effect that a remote JWKs source will be polled
exactly one additional time too for errors that have to do with
configuration, or for errors that might be caused by not synched
clocks, forged JWTs, etc. ( These will throw a BadJWTException
which extends BadJOSEException also )

Split search in two when made against throttled and non throttled searches (#42510)

When a search on some indices takes a long time, it may cause problems to other indices that are being searched as part of the same search request and being written to as well, because their search context needs to stay open for a long time. This is especially a problem when searching against throttled and non-throttled indices as part of the same request. The problem can be generalized though: this may happen whenever read-only indices are searched together with indices that are being written to. Search contexts staying open for a long time is only an issue for indices that are being written to, in practice.

This commit splits the search in two sub-searches: one for read-only indices, and one for ordinary indices. This way the two don't interfere with each other. The split is done only when size is greater than 0, no scroll is provided and query_then_fetch is used as search type. Otherwise, the search executes like before. Note that the returned num_reduce_phases reflect the number of reduction phases that were run. If the search is split in two, there are three reductions: one non-final for each search, and a final one that merges the results of the previous two.
