> 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.
