             Summary: CapacityScheduler should properly handle moving LeafQueue from one parent to another
                 Key: YARN-3764
                 URL: https://issues.apache.org/jira/browse/YARN-3764
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Wangda Tan
            Assignee: Wangda Tan
            Priority: Blocker


Currently CapacityScheduler doesn't handle the case well, for example:

A queue structure:
{code}
    root
      |
      a (100)
    /   \
   x     y
  (50)   (50)
{code}

And reinitialize using following structure:
{code}
     root
     /   \ 
(50)a     x (50)
    |
    y
   (100)
{code}

The actual queue structure after reinitialize is:
{code}
     root
    /    \
   a (50) x (50)
  /  \
 x    y
(50)  (100)
{code}

We should handle this case better.
