Sandy Ryza commented on YARN-1913:
----------------------------------

The "M" un Unmanaged AM shouldn't be capitalized.  Otherwise, the patch LGTM.

> With Fair Scheduler, cluster can logjam when all resources are consumed by AMs

> 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.
