Subject [jira] [Commented] (MAPREDUCE-5255) Reduce task preemption results in task never completing , incomplete fix to MAPREDUCE-3858 ?
Date Fri, 17 May 2013 23:29:16 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5255?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13661146#comment-13661146
] 

Rahul Jain commented on MAPREDUCE-5255:
---------------------------------------

Yes, it appears quite likely; will try the patch described in MAPREDUCE-5009 to verify if
it is the same issue.

>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: mrv2
>    Affects Versions: 2.0.3-alpha
>            Reporter: Rahul Jain
>
> The problem was seen with symptoms very similar to MAPREDUCE-3858: the job is hung with
continuous reduce task attempts, each attempt getting killed around commit phase.
> After a while the single reduce task was the only one remaining in the job, with 50K
'kills' done for the task.
> Relevant logs from application master:
