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

             Summary: FairScheduler should have a way of disabling the max AM share check
for launching new AMs
                 Key: YARN-2187
                 URL: https://issues.apache.org/jira/browse/YARN-2187
             Project: Hadoop YARN
          Issue Type: Bug
          Components: fairscheduler
    Affects Versions: 2.5.0
            Reporter: Robert Kanter
            Assignee: Robert Kanter


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.  We should
have a way of disabling this check to prevent this problem.
