Subject [jira] [Commented] (HADOOP-8851) Use -XX:+HeapDumpOnOutOfMemoryError JVM option in the forked tests
Date Mon, 01 Oct 2012 17:35:07 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8851?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13466986#comment-13466986

Ivan A. Veselovsky commented on HADOOP-8851:
--------------------------------------------

If you're using Jenkins (Hudson) builds, also it's good idea to save **/*.hprof artifacts
to protect the memory dumps from being deleted upon the workspace cleanup.
