Key: HADOOP-4391
URL: https://issues.apache.org/jira/browse/HADOOP-4391
Project: Hadoop Core
Issue Type: Bug
Reporter: Runping Qi
Many times we saw sub processes left still running after a streaming task is killed.
This is one kind of resource leakage.
The framework should kill the whole subprocess tree when killing a task.

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.
