Wei Yan commented on YARN-2385:
-------------------------------

The YarnScheduler.java already has a function which has implemented in 
Fifo/Fair/Capacity.
{code}
public List<ApplicationAttemptId> getAppsInQueue(String queueName);
{code}
Is this enough for this jira?

> Adding support for listing all applications in a queue

> 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
