                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1693

            Reporter: Vinay Kumar Thota

The following scenarios covered in the test.

1. Run a job which spawns subshells in the tasks. Kill one of the task. All the child process of the killed task must be killed.
2. Run a job which spawns subshells in tasks. Fail one of the task. All the child process of the killed task must be killed along with the task after its failure.
3. Check process tree cleanup on paritcular task-tracker when we use -kill-task and -fail-task with both map and reduce.
