Subject [jira] [Updated] (HADOOP-8851) Use -XX:+HeapDumpOnOutOfMemoryError JVM option in the forked tests
Date Mon, 01 Oct 2012 17:43:07 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-8851?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Aaron T. Myers updated HADOOP-8851:
-----------------------------------

          Component/s: test
     Target Version/s: 2.0.3-alpha
    Affects Version/s: 2.0.1-alpha

Thanks a lot for the info, Ivan, and for testing out the patch. I've also just tested out
this option with OpenJDK and confirmed that it works similarly to the Sun JDK.

I'm going to go ahead and commit this shortly.
