-----------------------------------------
Hi [~sunilg], Ideal would have been that Max-AM-Resource-Percentage can be
configured for per queue per partition then it would have been clear but at the
minimum i feel it should be 2nd option. In terms of debug ability in the case
which [~leftnoteasy] mentioned ??but also can lead to too many AMs launched
under a single partition??, if user is viewing the web ui, user need to see
each of the partitions which is accessible to the queue and find out which
partition is using more am resource and then try to resolve. But with the 2nd
option it would be clear whats Max-AM-Resource-Percentage per partition with
changes in UI to point AM resource usage per partition per queue.
> Max-AM-Resource-Percentage should respect node labels

> Currently, max-am-resource-percentage considers default_partition only. When
> a queue can access multiple partitions, we should be able to compute
> max-am-resource-percentage based on that.
