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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
