Subject [jira] [Commented] (YARN-4626) Scheduler UI make queue invisible for partition if not mapped with label

-----------------------------------------

Hi [~sunilg],
IMO its slightly related to the issue which i had mentioned in YARN-4415 (refer the attached
images which shows as 100% but the app diagnostic info doesn't launch as abs capacity &
max capacity is 0%).
Basically this issue is happening because when {{QueueCapacitiesInfo.getPartitionQueueCapacitiesInfo(String)}}
called for a particular partition if capacity information is not there then we create a *PartitionQueueCapacitiesInfo*
which takes 0 as capacity and *100* as max capacity (even we take 1 as the default value as
suggested by [~wangda]  we face the same problem). 
Both these values needs to be *zero* based on current implementation.  Size will get reset
to *0*, when there is non exclusive sharing of resources to this queue for apps in default
partitions as there will be an proper entry in {{QueueCapacities}} which was earlier not there.
Once we correct this then size is getting reset to zero will not be there on these particular
cases.

> Currently is  queue is not mapped with label then its displayed in scheduler UI. Once
an application is submitted the resource get  updated to zero.
