Alejandro Abdelnur commented on YARN-1241:
------------------------------------------
* FairScheduler.java
** false changes lines 192, 620, 709, 713
* MaxRunningAppsEnforcer.java
** Wouldn't make sense to make all the methods to take an AppSchedulable?
* FSLeafQueue.java
** instead keeping track of non runnable apps here, why not have a separate
data structure where to park the non runnable apps? Then the queues would never
see a non runnable app
* Unless I'm missing something we are tracking runnable apps only, are we
tracking non-runnable apps? If not, it would be handy to have an idea of the
demand of a queue
> In Fair Scheduler maxRunningApps does not work for non-leaf queues
