      Description

      The netgroups implementation of GroupMappingServiceProvider (see ShellBasedUnixGroupsNetgroupMapping.java) does a fork of a unix command to get the netgroups 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.

      Note that this is similar to what https://issues.apache.org/jira/browse/HADOOP-6818 does for implementation of GroupMappingServiceProvider that supports only unix groups.
