---------------------------------
Assignee: Vinod K V
> Duplicate destroy of process trees in TaskMemoryManager.
> --------------------------------------------------------
>
> Key: HADOOP-5428
> URL: https://issues.apache.org/jira/browse/HADOOP-5428
> Project: Hadoop Core
> Issue Type: Bug
> Components: mapred
> Reporter: Vinod K V
> Assignee: Vinod K V
> Priority: Minor
>
> TaskMemoryManager currently works only on Linux and terminates tasks that
> transgress memory-limits by first calling TaskTracker.purgeTask() and then
> explicitly destroying the process tree to be sure that the whole process tree
> is cleaned up. After HADOOP-2721, we don't need this explicit process-tree
> destroying as the usual code-path of killing tasks itself takes care of
> cleaning up the whole process-trees.
