Naganarasimha G R updated YARN-3717:
    Attachment: RMLogsForHungJob.log

Attaching the grep RM logs for the hung App, as the resources for the labels 
are not available. This is more visible when a queue's accessible label does 
not specify default partition(but by default its accessible) and user submit to 
this queue with out specifying partition. If no node is under default partition 
then the job will be hung

> Improve debug-ability of Node Labels

> Few improvements which i want to suggest are : 
> 1> Add the default-node-Label expression for each queue in WebUI 
> 2> In Application/Appattempt page  show the app configured node label 
> expression for AM and Job (may be we need to store in ATS too)
> 3> RM log for the application ID which has hung has been attached, it is 
> difficult to analyze as there is no information related to the labels in it . 
> I was intending to add @
