Subject [jira] [Commented] (HADOOP-7214) Hadoop /usr/bin/groups equivalent
Date Thu, 07 Apr 2011 23:49:06 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7214?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13017206#comment-13017206

Aaron T. Myers commented on HADOOP-7214:

bq. I don't think groups is POSIX... which is why it has different output on different platforms.
(Even if it was, POSIX rarely, if ever, defines the output format of those commands).

Even if it's not specified by POSIX, it seems like a good idea to make the output similar
to the groups command which is most-commonly used by users. I did this in the formatting of
the normal output, no reason not to do it in the case of error.

bq. In the case of our groups command, giving a username that isn't the caller's should be

Why? On every system I've ever used this hasn't been the case, so I don't see why it should
be the case here.

> Since user -> groups resolution is done on the NN and JT machines, there should be
a way for users to determine what groups they're a member of from the NN's and JT's perspective.
