Vinod K V commented on HADOOP-4391:
-----------------------------------
This can be addressed by introducing job control for tasks (HADOOP-2721).
Without which, tracking and killing sub-processes becomes intractable.
> When killing a streaming task, it should kill the sub processes (subtree)
> spawned by the task
