Yufei Gu commented on YARN-5554:
--------------------------------

Thanks [~wilfreds]'s new patch. It makes sense to not introduce more 
dependencies. Some nits:
1.
{code}  
  /*
   * Check access to a targetQueue in the case of a move of an application
{code}
The first line should be {{/**}}.
2. I am wondering
{code}
    if (scheduler instanceof CapacityScheduler) {
    ...
    } else if (scheduler instanceof FairScheduler) {
    ...
    } else {
    return ...
    }
{code} will be more readable.
3. In func {{moveApplicationAcrossQueues}}, can we use {{ioe.toString()}} 
instead of {{"Target queue does not exist " + targetQueue}}?

> MoveApplicationAcrossQueues does not check user permission on the target queue

> moveApplicationAcrossQueues operation currently does not check user
