Subject [jira] [Commented] (HADOOP-10401) ShellBasedUnixGroupsMapping#getGroups does not always return primary group first
Date Tue, 18 Mar 2014 18:43:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10401?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13939627#comment-13939627
] 

Chris Nauroth commented on HADOOP-10401:
----------------------------------------

I suggest && instead of ; for separating commands.  We wouldn't want to mask a failure
in the first command if the second command is successful.  (That kind of failure should be
a really really rare thing of course, but let's try to catch it just in case.)

 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.
