-----------------------------------------
[~jlowe] is this yet another {{System.exit()}}?! Wow, wondering how many times
we have to touch the code to fix this completely :)
> Timed out tasks can fail to produce thread dump
> -----------------------------------------------
>
> Key: MAPREDUCE-7053
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7053
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 3.1.0, 3.0.1, 2.10.0, 2.9.1, 2.8.4, 2.7.6
> Reporter: Jason Lowe
> Priority: Major
>
> 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.
