Subject [jira] Created: (MAPREDUCE-1869) TaskTracker hung in org.apache.hadoop.fs.LocalDirAllocator
Date Tue, 15 Jun 2010 22:57:23 GMT
TaskTracker hung in org.apache.hadoop.fs.LocalDirAllocator
----------------------------------------------------------

                 Key: MAPREDUCE-1869
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1869
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: tasktracker
    Affects Versions: 0.20.2
         Environment: Solaris 10 Update 7
Java 1.6.0_14
            Reporter: Allen Wittenauer
            Priority: Critical


A TaskTracker process on our grid appears to be locked up and not sending heartbeats to the
namenode.  Attaching jstack and pstack output.  Even tho the hangs appear to be in LocalDirAllocator,
the local file system seems to be a-ok.
