Subject [jira] [Commented] (YARN-3846) RM Web UI queue fileter not working
Date Sat, 27 Jun 2015 12:13:04 GMT

    [ https://issues.apache.org/jira/browse/YARN-3846?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14604131#comment-14604131
] 

Mohammad Shahid Khan commented on YARN-3846:
--------------------------------------------

https://issues.apache.org/jira/browse/YARN-2238 is for different fix.
The label "Queue  :" was added before the queue name in https://issues.apache.org/jira/browse/YARN-3362.
After the search was not working and the same has been handled in the  https://issues.apache.org/jira/browse/YARN-3707.
The fix is OK for the for the first child of the queue 
but will not work for the second child
for example Queue: b.x
       
  Queue: root
    Queue: a          _*For queue a it will work fine*_
    Queue: b    
       Queue: b.x   _*But for queue x and y this will not work*_
       Queue: b.y

*My question: *
  What is the significance of adding Label *"Queue:"*  before the queue name?

> 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 
> {code}
> q = '^' + q.substr(q.lastIndexOf(':') + 2) + '$';",
> {code}
> 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
