> 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.
