> Currently the RM log shows only a partial set of the limits that are configured when a queue is initialized / reinitialized.
> For example, this is what is currently shown in the RM log for an initialized queue:
> # <datestamp> INFO org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.LeafQueue: Initializing
> default, capacity=0.25, asboluteCapacity=0.25, maxCapacity=25.0, asboluteMaxCapacity=0.25, userLimit=100,
> userLimitFactor=20.0, maxApplications=2500, maxApplicationsPerUser=50000, state=RUNNING,
> acls=ADMINISTER_QUEUE:*SUBMIT_JOB:*ADMINISTER_JOBS:*
> Breaking down the line above, shows: 
> capacity=0.25
> asboluteCapacity=0.25
> maxCapacity=25.0
> asboluteMaxCapacity=0.25
> userLimit=100
> userLimitFactor=20.0
> maxApplications=2500
> maxApplicationsPerUser=50000
> It might be nice if we could include more information such as maxActiveApplications, maxActiveApplicationsPerUser, utilization, and usedCapacity along with information on how each of these is computed (i.e. formulae used) (Thanks to Phil Su for requesting this).
