Agree with Milind.
Todd, let me know if you plan to fix it soon.
Unblocking for now.
> With JVM reuse, JvmManager doesn't delete last workdir properly
> ---------------------------------------------------------------
>
> Key: MAPREDUCE-2268
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2268
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: tasktracker
> Reporter: Todd Lipcon
> Assignee: Todd Lipcon
> Fix For: 0.22.0
>
>
> In JvmManager, when a Jvm exits, it tries to delete the workdir for
> {{initalContext.task}} which is null, hence throwing NPE. Currently this NPE
> is swallowed into the abyss.
> We should catch exceptions out of the JvmRunner thread, add a test case that
> verifies this functionality, and fix this code to properly grab the last task.
