Vinay Kumar Thota updated MAPREDUCE-1693:
-----------------------------------------
Description:
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.
4. Submit a job which would spawn child processes and each of the child
processes exceeds the memory limits. Let the job complete . Check if all the
child processes are killed, the overall job should fail.
l)Submit a job which would spawn child processes and each of the child
processes exceeds the memory limits. Kill/fail the job while in progress. Check
if all the child processes are killed.
