-----------------------------

             Summary: In fair scheduler, Queue should not been assigned more 
containers when its usedResource had reach the maxResource limit
                 Key: YARN-2083
                 URL: https://issues.apache.org/jira/browse/YARN-2083
             Project: Hadoop YARN
          Issue Type: Bug
          Components: scheduler
    Affects Versions: 2.3.0
            Reporter: Yi Tian


In fair scheduler, FSParentQueue and FSLeafQueue do an assignContainerPreCheck 
to guaranty this queue is not over its limit.
But the fitsIn function in Resource.java did not return false when the 
usedResource equals the maxResource.

I think we should create a new Function "fitsInWithoutEqual" instead of 
"fitsIn" in this case.
