> 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.
