Capacity scheduler uses all slots from the same tasktracker

[Sulabh Choudhury]

Hi,

So I just started using capacity scheduler for M/R jobs. I have 4 task
trackers each with 4 map/reduce slots.
Configured a queue so that it uses 25% (4 slots) of the available slots. I
was expecting that it would distribute the job and use slots from each of
the 4 tasktrackers but it actually uses all 4 slots from a single TT.
Is there a configuration I am missing or this is the expected behavior ?
