Vinod Kumar Vavilapalli commented on YARN-1512:
-----------------------------------------------
Good that we are marking the configs private and the feature disabled by
default for now.
You have two sleeps inside the scheduler loop - one for 5ms and the 1sec sleep
in the scheduler thread. May be we should pull the 5ms wait into the caller and
also make it configurable so as to help tuning in large clusters depending on
the cost of the scheduling loop?
Looks fine enough to me otherwise.
