Subject [jira] [Commented] (MAPREDUCE-4463) JobTracker recovery fails with HDFS permission issue
Date Tue, 24 Jul 2012 22:29:34 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4463?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13421836#comment-13421836

Tom White commented on MAPREDUCE-4463:

Arun, I've seen an occasional race where the TT reinit actually causes removeTaskFromJob()
to be called just _after_ the equivalent recovered TIP has started, so the new TIP is erroneously
removed from rjob.tasks. This code protects from that happening. Does that sound reasonable?

than a pseudo-distributed cluster).
