That is true *only* if you do not have enough slots to run tasks for other jobs of the same user in the entire cluster. On Mar 5, 2013, at 9:02 PM, Jagmohan Chauhan wrote: > I think i need to re-frame the question a bit. Yes CS supports multiple > jobs in parallel but of different users. If i am

Thanks Harsh. I have a few more questions. Q1: I found it in my experiments using CS that for any user , its next job does not start until its current one is finished. Is it true and are there any exceptions and if true then why is it so? I I did not find any such condition in the implementation
