Jason Lowe commented on YARN-308:
---------------------------------
To clarify, I believe it is a semi-delta protocol. An ask for a particular
resource name overrides all prior asks for that resource name, but it does not
override prior asks for resource names not listed in the current ask. For
example, an initial ask only for host A followed by a subsequent ask only for
host B results in a combined ask for hosts A and B.

> 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?
