> JobTracker's TaskCommitQueue is vulnerable to non-IOExceptions

> Key: HADOOP-2051

> Project: Hadoop
> Issue Type: Bug
> Components: mapred
> Affects Versions: 0.15.0
> Reporter: Arun C Murthy

> The {{JobTracker#TaskCommitQueue#run}} method only handles {{IOException}}s.
> Christian Kunz ran into a scenario where a job was stuck with all tasks in
> {{COMMIT_PENDING}} state and the stack traces showed that the "Task Commit
> Thread" wasn't even around.
> The work-around is to model {{TaskCommitQueue#run}} along the lines of other
> long-running threads in the {{JobTracer}} ({{ExpireLaunchingTasks}},
> {{ExpireTrackers}} etc.) to catch, log and ignore any {{Exception}} in a loop.
