Naganarasimha G R commented on YARN-2495:
-----------------------------------------

Hi [~wangda], Thanks for the review
bq. 1) As same as ResourceTrackerService, it's better to have a field like isDecentralizedNodeLabelConfigurationEnabled
(or some other name you like) in NodeStatusUpdaterImpl. Should be more clear than statement
like
Earlier in one of your [comment|https://issues.apache.org/jira/browse/YARN-2495?focusedCommentId=14183135&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14183135],
you had mentioned as 
{quote}
5) NodeStatusUpdaterImpl:
isDecentralizedNodeLabelsConf may not need here, if nodeLablesProvider passed in is null.
That means isDecentralizedNodeLabelsConf is false.
+            nodeLabelsForHeartBeat = null;
+            if (isDecentralizedNodeLabelsConf) {
...
{quote}
so had changed it , may be earlier you meant some thing else and i read the comment wrongly
?

for 2 & 3 will rework and share the patch, but hope test cases are fine too ?
