Balaji Rajagopalan commented on MAPREDUCE-1693:
-----------------------------------------------
GenerateTaskChildProcess is not there in the final patch, but it is available
in the previous patch.
Also in the final patch there is utility methods for start/stop cluster this a
duplicate of what is there in the other patch, please clean up this issues.
I need one patch which has all the changes for task killing, also mentioned
this patch is depend on utility method patch, that is dependent on push config
patch. This will clearly give me the sequence in which the patches will be
committed.
> Process tree clean up of either a failed task or killed task tests.

> 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.

> 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.
