[jira] [Created] (HADOOP-17505) public interface GroupMappingServiceProvider needs default impl for getGroupsSet()

Vinayakumar B created HADOOP-17505:
--------------------------------------

             Summary: public interface GroupMappingServiceProvider needs default impl for getGroupsSet() 
                 Key: HADOOP-17505
                 URL: https://issues.apache.org/jira/browse/HADOOP-17505
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Vinayakumar B


HADOOP-17079 added "GroupMappingServiceProvider#getGroupsSet()" interface.

But since this is a public interface, it will break compilation of existing implementations in downstreams.

Consider adding a default implementation in the interface to avoid such failures.
