Date Tue, 26 May 2015 15:19:17 GMT
Naganarasimha G R created YARN-3717:
---------------------------------------

             Summary: Improve debug-ability of Node Labels
                 Key: YARN-3717
                 URL: https://issues.apache.org/jira/browse/YARN-3717
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Naganarasimha G R
            Assignee: Naganarasimha G R


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 @
"2015-05-26 00:19:25,681 INFO org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.LeafQueue:
Application added - appId: application_1432579630889_0001 user: org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.LeafQueue$User@35b4193e,
leaf-queue: default #user-pending-applications: 0 #user-active-applications: 1 #queue-pending-applications:
0 #queue-active-applications: 1" open for suggestions for adding Info logs
