I am using Capacity scheduler on a  cluster of 5 nodes. I submit 3 jobs to the system with a single queue for same user. I am observing that they are executed on FIFO basis even if the map slots are empty.  According to my observation , when the first job for the user ends then its 2nd job starts.

Is it true that when using Capacity Scheduler, for any user, its next job will be executed when its prior job is finished?

Thanks and Regards
