Cheng Lian created SPARK-18451:
----------------------------------
Summary: 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
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.
