[jira] [Commented] (MAPREDUCE-5711) When JobTracker writing JobHistory to HDFS, it may hung for long time due to DataNode error

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13866881#comment-13866881 ]

------------------------------------------

Thanks for working on this!  I think it's a duplicate of MAPREDUCE-1144.  Additionally, I think MAPREDUCE-5606 is a duplicate of the same issue.  Can you please take a look at MAPREDUCE-1144?  If you agree that it's the same problem, then I recommend closing this as duplicate and moving your patch over to MAPREDUCE-1144.

> When writing JobHistory to HDFS, it may takes very long time due to DataNode error, unfortunately, it also hold JobTracker lock, so it makes JobTracker hung for long time. It happens couple of times on our cluster.
