> Project: Hadoop Map/Reduce
> Issue Type: Improvement

> 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).
