Sunil G commented on YARN-2385:
-------------------------------
I am not sure whether we need to check about completed apps for CS and Fair?
Only in this case of having completed apps, we have problem of evicting apps
beyond a limit as mentioned by [~wangda] in YARN-807.
May be two separate apis (getRunningAppsInQueue, getPendingAppsInQueue) with
common behavior across CS/Fair could be a better approach.
> Adding support for listing all applications in a queue

> Key: YARN-2385
> URL: https://issues.apache.org/jira/browse/YARN-2385
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: capacityscheduler, fairscheduler
> Reporter: Subramaniam Venkatraman Krishnan
> Assignee: Karthik Kambatla
> Labels: abstractyarnscheduler
>
> This JIRA proposes adding a method in AbstractYarnScheduler to get all the
> pending/active applications. Fair scheduler already supports moving a single
> application from one queue to another. Support for the same is being added to
> Capacity Scheduler as part of YARN-2378 and YARN-2248. So with the addition
> of this method, we can transparently add support for moving all applications
> from source queue to target queue and draining a queue, i.e. killing all
> applications in a queue as proposed by YARN-2389
