Scott Chen commented on MAPREDUCE-220:
--------------------------------------
Had some offline discussion with Dhruba.
We can make COUNTER_UPDATE_INTERVAL configurable here (it is currently hard
coded to 1 min).
Then we can reconfigure it to submit newer information to the scheduler in our
case.
This should solve our problem.
