I just did a manual testing of this.

with -java-home "jdk", setting just JAVA_HOME and both. Hope it covers all cases.

@pwendell Hey Patrick, It might be good to have jenkins not test the PRs which start with [WIP] or WIP. Or something like that ?

It does not cover the case if JAVA_HOME points to invalid directory, it will simply take alternate path instead of failing nicely.

Fix mesos urls

This was a bug I introduced in https://github.com/apache/incubator-spark/pull/71.
Previously, we explicitly removed the mesos:// part; with alteryx#71, this no longer occurs.

…s internal aggregation buffer object

## What changes were proposed in this pull request?

(This PR cherry-picks PR apache#14753 to Databricks Spark branch-2.0.)

This PR introduces an abstract class `TypedImperativeAggregate` so that an aggregation function of TypedImperativeAggregate can use  **arbitrary** user-defined Java object as intermediate aggregation buffer object.

**This has advantages like:**
1. It now can support larger category of aggregation functions. For example, it will be much easier to implement aggregation function `percentile_approx`, which has a complex aggregation buffer definition.
2. It can be used to avoid doing serialization/de-serialization for every call of `update` or `merge` when converting domain specific aggregation object to internal Spark-Sql storage format.
3. It is easier to integrate with other existing monoid libraries like algebird, and supports more aggregation functions with high performance.

Please see `org.apache.spark.sql.TypedImperativeAggregateSuite.TypedMaxAggregate` to find an example of how to defined a `TypedImperativeAggregate` aggregation function.
Please see Java doc of `TypedImperativeAggregate` and Jira ticket SPARK-17187 for more information.

## How was this patch tested?

Unit tests.
