> Final map task gets stuck
> -------------------------
>
> Key: HADOOP-707
> URL: http://issues.apache.org/jira/browse/HADOOP-707
> Project: Hadoop
> Issue Type: Bug
> Components: mapred
> Affects Versions: 0.8.0
> Environment: using latest trunk
> Reporter: Johan Oskarson
> Priority: Critical
>
> I've seen numerous jobs lately where the final map task gets stuck, never
> finishing.
> The jobtracker doesn't reassign the task. A restart of the tasktracker solves
> the issue and the job can finish.
> In the web interface it turns up as:
> task_0028_m_000534_0 node17.herd1 RUNNING 0.00% 10-Nov-2006 12:21:12
> 10-Nov-2006 12:22:19 (1mins, 6sec)
> Task failed to report status for 604 seconds. Killing.
> Only exception I find in that tasktracker log is this (a few times):
> java.nio.channels.ClosedChannelException
> at
> sun.nio.ch.SocketChannelImpl.ensureWriteOpen(SocketChannelImpl.java:125)
> at sun.nio.ch.SocketChannelImpl.write(SocketChannelImpl.java:294)
