-----------------------------------------
Summary: Add NullGroupMapping
Key: HADOOP-12566
URL: https://issues.apache.org/jira/browse/HADOOP-12566
Project: Hadoop Common
Issue Type: Improvement
Reporter: Daniel Templeton
Assignee: Daniel Templeton
Add a {{NullGroupMapping}} for cases where user groups are not used.
{{ShellBasedUnixGroupMapping}} can be used in places where latency is not
important. In places like starting a container, it's worth in to avoid the
extra fork and exec.
