Bikas Saha commented on YARN-275:
---------------------------------
Right. For the first step, the ResourceTrackerService (that sends the response
back to the NM heartbeat) should send a heartbeat interval value back in the
response. That value should be read from config.
> Make NodeManagers to NOT blindly heartbeat irrespective of whether previous
> heartbeat is processed or not.
