> Leaf queues maintain a list of runnable and non-runnable apps. FairScheduler 
> marks an app non-runnable for different reasons: exceeding (1) queue max 
> apps, (2) user max apps, (3) queue maxResources, (4) maxAMShare. It would be 
> nice to log the reason an app isn't runnable. The first three are easy to 
> infer, but the last one (maxAMShare) is particularly hard. It would be nice 
> to log at least that.
