Devaraj Das commented on HADOOP-1900:
-------------------------------------
I think in my last proposal, the adaptiveness is not going to be that much of
an overkill since I am only suggesting that we just monitor the average time to
process an RPC. That will take care of things like beefy hardware vs
rudimentary ones...
> the heartbeat and task event queries interval should be set dynamically by
> the JobTracker
