[jira] [Commented] (MAPREDUCE-1506) Assertion failure in TestTaskTrackerMemoryManager

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13018002#comment-13018002 ] 

Nigel Daley commented on MAPREDUCE-1506:
----------------------------------------

Any volunteers to look at this for 0.22?  If not, I'd suggest punting this as a blocker to 0.23.

> With asserts enabled, TestTaskTrackerMemoryManager sometimes fails. From what I've inspected, it's because some tasks are marked as FAILED/TIPFAILED while others are marked SUCCEEDED.
> This can be reproduced by applying MAPREDUCE-1092 and then running {{ant clean test -Dtestcase=TestTaskTrackerMemoryManager}}
