Sandy Ryza commented on YARN-308:
---------------------------------
That's right Jason. Each resource request in the heartbeat's list overwrites
any previous requests at its priority and locality, but requests at different
priorities and localities are unaffected.
Would changing it to be a pure absolute or pure delta protocol break things?
It seems like this would be easier to understand.

> It's unclear to me from reading the javadoc exactly what "asks" means when
> the AM sends a heartbeat to the RM. Is the AM supposed to send a list of all
> resources that it is waiting for? Or just inform the RM about new ones that
> it wants?
