Provide a JNI-based implementation of GroupMappingServiceProvider
-----------------------------------------------------------------

                 Key: HADOOP-6818
                 URL: https://issues.apache.org/jira/browse/HADOOP-6818
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
            Reporter: Devaraj Das
            Assignee: Devaraj Das
             Fix For: 0.22.0


The default implementation of GroupMappingServiceProvider does a fork of a unix command to
get the groups of a user. Since the group resolution happens in the servers, this might be
costly. This jira aims at providing a JNI-based implementation for GroupMappingServiceProvider.
