             Summary: RM Web UI queue fileter not working
                 Key: YARN-3846
             Project: Hadoop YARN
          Issue Type: Bug
          Components: yarn
    Affects Versions: 2.7.0
            Reporter: Mohammad Shahid Khan

Click on root queue will show the complete applications
But click on the leaf queue is not filtering the application related to the the 
clicked queue.

The regular expression seems to be wrong 
q = '^' + q.substr(q.lastIndexOf(':') + 2) + '$';",

For example
1. Suppose  queue name is  b
them the above expression will try to substr at index 1 
q.lastIndexOf(':')  = -1
-1+2= 1
which is wrong. its should look at the 0 index.

2. if queue name is ab.x
    then it will parse it to .x 
    but it should be x
