Description

This is a regression from Hadoop1, as hadoop mrgroups fails with:

Exception in thread "main" java.lang.UnsupportedOperationException
	at org.apache.hadoop.mapred.tools.GetGroups.getProtocolAddress(GetGroups.java:50)
	at org.apache.hadoop.tools.GetGroupsBase.getUgmProtocol(GetGroupsBase.java:98)
