Subject Max Application Master Resources with Queue Elasticity
Date Tue, 07 Feb 2017 03:50:22 GMT

I noticed that "Max Application Master Resources" on the ResourceManager UI
(/cluster/scheduler) takes into account queue elasticity.

AMResourceLimit and userAMResourceLimit on the ResourceManager API
(/ws/v1/cluster/scheduler) also takes into account queue elasticity.

Are these AM resources always guaranteed? If a queue cannot grow because
all of the other queues in the cluster are fully utilized, does the queue
still have "Max Application Master Resources" available for AM containers?
