Hi Vinod,
Thanks for the review.
Let me explain why I did the changes the way it is in the patch.
In CLI.java, Kill job code path calls this
Job job = cluster.getJob(JobID.forName(jobid));
Which actually result in to the client.getstatus.
When we create the client object it checks if the history server is
configured and if yes then it creates the proxy. Once the client is
created it gets cached in the client cache which is been used for all
the calls.
Now, for any call we use this client object from the cache and in kill
command we use that as well and thats when all the calls are
transferred to History server.
What we are trying to do here is for kill only we dont want to go to
History server so we can not use the same client object from the cache
otherwise it will go to HS. However we need client object which
has History server references for all other calls because think about
the situation when client get the job status with HS which returns
counters etc in this case if we replace client object (without HS)
then client code will start failing (Thanks to Sid pointing this case
out to me).
So for kill command we need client object without HS.
As you suggested ClientServiceDelegate.getProxy() should take some
parameter however it can not be done as actually the call is not kill it
is getjobstatus.
For minimrcluster I think we can not get the History server handle
directly and tharts the reason I made that change.
Let me do the change for KillTask.
Let me know your thoughts.
Thanks,
Mayank

This test is already failing in the trunk and unrelated to this change. I am

The issue as reported without HISTORY server up if configured , user can not
kill the job.
History server does not do anyways in case of kill so in my patch I am short
circuiting the History server in case of kill.
Adding the test case for testing this scenario in case of History server is up
and down.
Thanks,
Mayank

Yes, it's still happening for me. From a recent trunk pull on a single-node
cluster where the history server isn't running yet:
{noformat}

...
{noformat}
And here's what it says after I start the history server:
{noformat}
$ mapred job -kill job_1344038428359_0002
2012-08-04 00:12:52,226 INFO mapred.ClientServiceDelegate

application_1344038428359_0002
Killed job job_1344038428359_0002
{noformat}
Note that in both cases it says the application state is completed and is
redirecting. If the application state is completed, there's no point in
redirecting to the history server if we're trying to kill the application.
Knowing the application state is completed means we can short-circuit the kill
attempt before the redirect.
