             Summary: Get-queue-mapping should be a common interface of 
YarnScheduler
                 Key: YARN-3635
                 URL: https://issues.apache.org/jira/browse/YARN-3635
             Project: Hadoop YARN
          Issue Type: Bug
          Components: scheduler
            Reporter: Wangda Tan
            Assignee: Wangda Tan


Currently, both of fair/capacity scheduler support queue mapping, which makes 
scheduler can change queue of an application after submitted to scheduler.

One issue of doing this in specific scheduler is: If the queue after mapping 
has different maximum_allocation/default-node-label-expression of the original 
queue, {{validateAndCreateResourceRequest}} in RMAppManager checks the wrong 
queue.

I propose to make the queue mapping as a common interface of scheduler, and 
RMAppManager set the queue after mapping before doing validations.
