Hyukjin Kwon resolved SPARK-18451.
----------------------------------
Resolution: Incomplete
> Always set -XX:+HeapDumpOnOutOfMemoryError for Spark tests
> ----------------------------------------------------------
>
> Key: SPARK-18451
> URL: https://issues.apache.org/jira/browse/SPARK-18451
> Project: Spark
> Issue Type: Bug
> Components: Build, Tests
> Reporter: Cheng Lian
> Priority: Major
> Labels: bulk-closed
>
> It would be nice if we always set {{-XX:+HeapDumpOnOutOfMemoryError}} and
> {{-XX:+HeapDumpPath}} for open source Spark tests. So that it would be easier
> to investigate issues like SC-5041.
> Note:
> - We need to ensure that the heap dumps are stored in a location on Jenkins
> that won't be automatically cleaned up.
> - It would be nice to be able to customize the customize the heap dump output
> paths on a per build basis so that it's easier to find the heap dump file of
> any given build.
> The 2nd point is optional since we can probably identify wanted heap dump
> files by looking at the creation timestamp.
