-----------------------------------------

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.

> 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.
