Subject killJob method in JobClient
Date Tue, 02 Dec 2008 04:39:10 GMT
I have some code where I create my own Hadoop job and the use the JobClient
to submit the Hadoop job. I noticed that the JobClient class has a
killJob() method. I was planning to play around and try to kill a running
Hadoop job. Does anybody know status the killJob method? I'm using Hadoop My concern is that it might work in some phases (map, reduce, etc)
of a Hadoop job, but not in other phases which is hard to find with simple
testing. There may be hidden gotchas that are hard to detect. This concern
is really driven by the fact that the jobtracker.jsp in Hadoop doesn't have
an option to kill a job. This would be a useful option.
