      Description

      Say you have a small cluster with 8gb memory and 5 queues. This means that equal queue can have 8gb / 5 = 1.6gb but an AM requires 2gb to start so no AMs can be started. By default, max-am-share check should be disabled so users don't see a regression. On medium-sized clusters, it still makes sense to set the max-am-share to a value between 0 and 1.
