MR AM hangs when one node goes bad

                 Key: MAPREDUCE-3228
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3228
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: applicationmaster, mrv2
    Affects Versions: 0.23.0
            Reporter: Vinod Kumar Vavilapalli
            Priority: Blocker
             Fix For: 0.23.0

Found this on one of the gridmix runs, again. One of the nodes went real bad, the job had
three containers running on the node. Eventually, AM marked the tasks as timedout and initiated
cleanup of the failed containers via {{stopContainer()}}. The later got stuck at the faulty
node, the tasks are stuck in FAIL_CONTAINER_CLEANUP stage and the job lies in there waiting
for ever.

Thanks to [~Karams] for helping with this.
