HADOOP--116 doubt

[Raghavendra Prabhu <rr...@gmail.com>]

Hi Doug

But Does not it wait in a loop until the job is complete?

It seemed that files are getting created when a job is submitted by the
client

Am i missing something here?

What i saw was theat

JobClient does a submitJob which creates the /tmp/mapred/hadoop/system files

Then it waits for it to complete in the while loop (!running.isComplete())

and at the end of it i delete the files.(the above /tmp/mapred/hadoop/system
files

Is there anything else which uses the above files even after the above run
is complete???

Maybe i am not familiar with the architecture (as per my previous mail)

Yes, but if one types Control-C, or the submitting workstation is 
rebooted, etc., then the job continues to run.  So the cleanup is best 
done when the job completes rather than when the submitter exits. 
Usually those are the same time, but not always.
