[jira] [Updated] (YARN-2753) Fix potential issues and code clean up for *NodeLabelsManager

     [ https://issues.apache.org/jira/browse/YARN-2753?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Wangda Tan updated YARN-2753:
-----------------------------
    Description: 
Issues include:

* CommonNodeLabelsManager#addToCluserNodeLabels should not change the value in labelCollections if the key already exists otherwise the Label.resource will be changed(reset).
* potential NPE(NullPointerException) in checkRemoveLabelsFromNode of CommonNodeLabelsManager.
** because when a Node is created, Node.labels can be null.
** In this case, nm.labels; may be null. So we need check originalLabels not null before use it(originalLabels.containsAll).
* addToCluserNodeLabels should be protected by writeLock in RMNodeLabelsManager.java. because we should protect labelCollections in RMNodeLabelsManager.
* Fix a potential bug in CommonsNodeLabelsManager, after serviceStop(...) is invoked, some event may not be processed
