Ajay Kumar created HADOOP-15333:

             Summary: Depreciate or remove Groups#getUserToGroupsMappingServiceWithLoadedConfiguration
                 Key: HADOOP-15333
                 URL: https://issues.apache.org/jira/browse/HADOOP-15333
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Ajay Kumar
            Assignee: Ajay Kumar

Groups#getUserToGroupsMappingServiceWithLoadedConfiguration introduced in YARN-1676 reinitializes
its static instance i.e \{{GROUPS}}. This  instance is stored by UGI for local reference.
Use of getUserToGroupsMappingServiceWithLoadedConfiguration results in UGI reference detached
from Parent class. This jira intends to discuss probable removal or depreciation of this function
to remove innocuous bug resulting from it.
