Subject [jira] [Updated] (MAPREDUCE-4576) Large dist cache can block tasktracker heartbeat
Date Mon, 27 Aug 2012 17:56:07 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-4576?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Robert Joseph Evans updated MAPREDUCE-4576:
-------------------------------------------

    Attachment: MR-4576.txt

This patch changes the locking on CacheStatus.  I have not added in any new tests because
it is a complicated bug, that is difficult to reproduce outside of a full cluster.  branch-1
seems to have a build issue so I have tested it against 1.0.2.  The commit tests pass, and
the smoke tests are still running.  I will also verify that it fixes the issue manually once
the other tests finish.
