Xianyin Xin commented on YARN-4415:
-----------------------------------
+1 for the general idea from [~Naganarasimha]. I think there exists many
improper in the code, especially when dealing with label "*", like
{{setupQueueConfigs()}} in {{AbstractCSQueue}} and, the
{{PartitionQueueCapacitiesInfo}} and {{QueueCapacitiesInfo}} when return the
actually capacities. I suggest you just upload a preview patch so that the
problem can exposed in another way, sounds feasible?
> Scheduler Web Ui shows max capacity for the queue is 100% but when we submit
> application doesnt get assigned

> Key: YARN-4415
> URL: https://issues.apache.org/jira/browse/YARN-4415
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: capacity scheduler, resourcemanager
> Affects Versions: 2.7.2
> Reporter: Naganarasimha G R
> Assignee: Naganarasimha G R
> Attachments: App info with diagnostics info.png,
> capacity-scheduler.xml, screenshot-1.png

> Steps to reproduce the issue :
> Scenario 1:
> # Configure a queue(default) with accessible node labels as *
> # create a exclusive partition *xxx* and map a NM to it
> # ensure no capacities are configured for default for label xxx
> # start an RM app with queue as default and label as xxx
> # application is stuck but scheduler ui shows 100% as max capacity for that
> queue
> Scenario 2:
> # create a nonexclusive partition *sharedPartition* and map a NM to it
> # ensure no capacities are configured for default queue
> # start an RM app with queue as *default* and label as *sharedPartition*
> # application is stuck but scheduler ui shows 100% as max capacity for that
> queue for *sharedPartition*
> For both issues cause is the same default max capacity and abs max capacity
> is set to Zero %
