Harsh J commented on MAPREDUCE-4431:
------------------------------------

Thanks Devaraj. Couple of points:

* In case of a job -kill on killed, failed or succeeded jobs, given your patch, we'll get a very ambiguous: "Could not kill the Job since the Job State is {KILLED,FAILED,SUCCEEDED}.".
** Perhaps we can instead check for state better and say things in each case thats more apt/intelligible.
*** "Could not kill the job <job ID>, as it has already succeeded."
*** "Could not mark the job <job ID> as killed, as it has already failed."
*** "The job <job ID> has already been killed."
* Can we have a test for this? That is, if we're trying to prevent a double killJob() calls to the AM/cluster.

bq. In case the job was already killed, should we perhaps return 0 exitCode (since the kill was (already) successful?

On second thought, lets not do this, as it would be in violation of what a command's run means. Only if the command were truly successful for that very instance we should return 0. So +1 and committing shortly.

Harsh J commented on MAPREDUCE-4431:
------------------------------------

+1, looks good to me too.

One comment though (just want your thought):

{code}
+            System.out.println("The job " + jobid + " has already been killed.");
+            exitCode = -1;
{code}

In case the job was already killed, should we perhaps return 0 exitCode (since the kill was (already) successful?
