---------------------------------------------
Summary: ShellBasedUnixGroupsMapping#getGroups does not always
return primary group first
Key: HADOOP-10401
URL: https://issues.apache.org/jira/browse/HADOOP-10401
Project: Hadoop Common
Issue Type: Bug
Components: util
Affects Versions: 2.4.0
Reporter: Colin Patrick McCabe
{{ShellBasedUnixGroupsMapping#getGroups}} does not always return the primary
group first. It should do this so that clients who expect it don't get the
wrong result. We should also document that the primary group is returned first
in the API. Note that {{JniBasedUnixGroupsMapping}} does return the primary
group first.
