Before	After

`StrictDynamicMappingException` occurred	not occurred

When applying and then deleting the auto follow rule in the CCR Plugin(cross-cluster-replication), the .tasks index is properly updated without StrictDynamicMappingException.

[Background]

OpenSearch allows a Follower Cluster to replicate indexes from a Leader Cluster through the Opensearch CCR Plugin.
However, when cancelling the auto follow rule in the CCR Plugin, a StrictDynamicMappingException was previously encountered:

[2024-09-28T12:01:16,819][WARN ][o.o.r.t.a.AutoFollowTask ] [5460424aac92][my-connection-alias] Error storing result StrictDynamicMappingException[mapping set to strict, dynamic introduction of [cancellation_time_millis] within [task] is not allowed]

When a task is stored, OpenSearch’s TaskResultsService.storeResult(TaskResult taskResult, ActionListener<Void> listener) is called.
This method extracts a TaskInfo object from theTaskResult parameter. TaskInfo defines the necessary fields for a task, which are mapped to the .tasks index via task-index-mapping.json.
So, when a task is cancelled, the .tasks index should be updated
Also, the .tasks index has strict dynamic mapping enabled.
However, cancellation_time_millis and resource_stats were present in TaskInfo but missing from the mapping JSON.
As a result, this was causing a StrictDynamicMappingException.

[PR contents]

Added the cancellation_time_millis and resource_stats fields to task-index-mapping.json:

...
          "cancellation_time_millis": {
            "type": "long"
          },
          "resource_stats": {
            "type" : "object",
            "enabled" : false
          }
...

Updated the mapping version in both task-index-mapping.json and TaskResultsService from 4 to 5.
These versions must match for the mapping to apply correctly. When updating a mapping, increment the version so future operations can detect and apply changes.

[Test]

I conducted two types of tests:

Writing a test in OpenSearch
Running local end-to-end (e2e) tests

Writing a test in OpenSearch

TaskInfo has two constructors: one that includes cancellation_time_millis (a) and one that does not (b).
In the existing TasksIT, the resultsService.storeResult() test did not include the appropriate resource_stats and cancellation_time_millis in the TaskInfo.
So, I added testStoreResultWithAllFields, using constructor (b) to create a test that only passes with the updated task-index-mapping.json.

Local End-to-End (e2e) Testing

To perform the e2e test, I needed a setup with two custom OpenSearch 3.0.0v clusters and the CCR Plugin 3.0.0v installed.

I set up two clusters with the CCR Plugin installed. I cloned the OpenSearch GitHub repository and modified the task-index-mapping.json.
After modifying OpenSearch, I assemble it, generating the opensearch-min-3.0.0-SNAPSHOT-linux-arm64.tar.gz file.
I then cloned and assembled the OpenSearch CCR GitHub repository, which generated opensearch-cross-cluster-replication-3.0.0.0-SNAPSHOT.zip.
Using a Dockerfile, I built a Docker image. In the same directory as the Dockerfile, I included the following files:
opensearch-min-3.0.0-SNAPSHOT-linux-arm64.tar.gz, opensearch-cross-cluster-replication-3.0.0.0-SNAPSHOT.zip, opensearch.yml, opensearch-docker-entrypoint.sh, opensearch-onetime-setup.sh

I used Docker Compose to create two clusters.
Finally, I installed the CCR plugin on each cluster:

docker exec -it [container] /bin/bash
/usr/share/opensearch/bin/opensearch-plugin install file:/usr/share/opensearch/opensearch-cross-cluster-replication-3.0.0.0-SNAPSHOT.zip

I registered an auto follow rule and then canceled it to verify the behavior. Set up a cross-cluster connection, get-started-with-auto-follow:

curl -XPUT -k -H 'Content-Type: application/json'  'http://localhost:9200/_cluster/settings?pretty' -d '
{
  "persistent": {
    "cluster": {
      "remote": {
        "my-connection-alias": {
          "seeds": ["localhost:9300"]
        }
      }
    }
  }
}'

curl -XPUT -k -H 'Content-Type: application/json'  'http://localhost:9201/leader-01?pretty'

curl -XPOST -k -H 'Content-Type: application/json' -u 'admin:Yhj99!009' 'https://localhost:9200/_plugins/_replication/_autofollow?pretty' -d '
{
   "leader_alias" : "my-connection-alias",
   "name": "my-replication-rule",
   "pattern": "movies*",
   "use_roles":{
      "leader_cluster_role": "all_access",
      "follower_cluster_role": "all_access"
   }
}'

curl -XDELETE -k -H 'Content-Type: application/json'  'http://localhost:9200/_plugins/_replication/_autofollow?pretty' -d '
{
   "leader_alias" : "my-connection-alias",
   "name": "my-replication-rule"
}'

I checked the logs to confirm if StrictDynamicMappingException occurred. After modifying the task-index-mapping.json correctly, I observed that instead of the previous StrictDynamicMappingException, the task status was successfully updated.

My test environment was Mac OS M2. If you are using a different operating system, replace the .tar.gz file with the version that matches your system.

If needed, I am happy to provide the Docker image used in my test. Please feel free to request it if required.

The local tests succeed, but they fail on “Gradle Check (Jenkins) / gradle-check (pull_request_target)” even though I haven’t modified them.
What actions should be taken?

dbwiddis · 2024-10-19T17:30:09Z

What actions should be taken?

Looks like two test failures:

There's no index test. Investigate why that is.
Your max hits expected and actual mismatch. This is a change in Lucene 9 where search hits gives a minimum bound (to save time) if an explicit value isn't requested. See Fix AbstractStringFieldDataTestCase tests to account for TotalHits lower bound #4270 for example on how to properly test this.
