Wangda Tan commented on YARN-4678:
----------------------------------
[~brahmareddy],
Are you using latest branch-2 or trunk to run the test?
bq. I think, will it make confusion ..? as sunil mentioned we are giving
metrics for both resereved and used.. I feel, subracting from used should be ok.
It will be fine after we can show reserved / allocated separately on the UI.
> Cluster used capacity is > 100 when container reserved

> *Scenario:*
> * Start cluster with Three NM's each having 8GB (cluster memory:24GB).
> * Configure queues with elasticity and userlimitfactor=10.
> * disable pre-emption.
> * run two job with different priority in different queue at the same time
> ** yarn jar hadoop-mapreduce-examples-2.7.2.jar pi -Dyarn.app.priority=LOW
> -Dmapreduce.job.queuename=QueueA -Dmapreduce.map.memory.mb=4096
> -Dyarn.app.mapreduce.am.resource.mb=1536
> -Dmapreduce.job.reduce.slowstart.completedmaps=1.0 10 1000000000000
> ** yarn jar hadoop-mapreduce-examples-2.7.2.jar pi -Dyarn.app.priority=HIGH
> -Dmapreduce.job.queuename=QueueB -Dmapreduce.map.memory.mb=4096
> -Dyarn.app.mapreduce.am.resource.mb=1536 3 1000000000000
> * observe the cluster capacity which was used in RM web UI
