Eric Payne commented on YARN-9930:
----------------------------------
bq. Which i want to do in this patch is that pending application but not
reject the application when the running app's number is over than given
threshold
[~cane], can you please clarify the use case? If I understand correctly, you
are saying that the pending application should not be rejected even if the
number of running apps is over the max threshold?
Here is the definition of maxRunningApps from
https://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/FairScheduler.html#Configuration
bq. maxRunningApps: limit the number of apps from the queue to run at once
> Support max running app logic for CapacityScheduler
