Subject Is there a way to pause a running hadoop job?
Date Thu, 02 Oct 2008 00:44:25 GMT
I have 5 running jobs, each has 2 reducers. Because I set max number of reducers as 10 so any
incoming job will be hold until some of the 5 jobs finish and release reducer quota. 

Now the problem is that an incoming job has a higher priority that I want to pause some of
the 5 jobs, let the new job finish, and resume the old one. 

Is this doable in Hadoop? Thanks!
