> TestMRJobs#testThreadDumpOnTaskTimeout has been failing sporadically
> recently. When the AM times out a task it immediately removes it from the
> list of known tasks and then connects to the NM to request a thread dump
> followed by a kill. If the task heartbeats in after the task has been
> removed from the list of known tasks but before the thread dump signal
> arrives then the task can exit with a "org.apache.hadoop.mapred.Task: Parent
> died." message and no thread dump.
