[jira] [Created] (HADOOP-10401) ShellBasedUnixGroupsMapping#getGroups does not always return primary group first

Colin Patrick McCabe created HADOOP-10401:
---------------------------------------------

             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.
