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.
