>                 URL: https://issues.apache.org/jira/browse/YARN-1913
>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: scheduler
>    Affects Versions: 2.3.0
>            Reporter: bc Wong
>
> It's possible to deadlock a cluster by submitting many applications at once, and have all cluster resources taken up by AMs.
> One solution is for the scheduler to limit resources taken up by AMs, as a percentage of total cluster resources, via a "maxApplicationMasterShare" config.
