[jira] Commented: (HADOOP-2367) Get representative hprof information from tasks

    [ https://issues.apache.org/jira/browse/HADOOP-2367?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12549326 ] 

Owen O'Malley commented on HADOOP-2367:
---------------------------------------

The race condition between the subprocess finishing and the event being sent out seemed out of scope for this bug, so I created a new one. HADOOP-2375.

> It would be great to get a representative (2 or 3) sample of builtin java profiler for a sample of maps and reduces. I'd store the information in the userlog directory and make it available in the local file system of the submitting application.
