> ------------------------------------------------------------------------------

> Key: YARN-1913
> 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
> Assignee: Karthik Kambatla
>
> 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.
