Subject [jira] [Commented] (MAPREDUCE-2376) test-task-controller fails if run as a userid < 1000
Date Wed, 29 Jun 2011 21:52:28 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2376?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13057493#comment-13057493
] 

Wing Yew Poon commented on MAPREDUCE-2376:
------------------------------------------

On CentOS 5.5 (and possibly other systems), non-system users have id >= 500, not 1000.
The test should check that the user id is between UID_MIN and UID_MAX in /etc/login.defs of
the system.
We are being bitten by this issue on our kerberos-secured cluster.

> test-task-controller tries to verify that the task-controller won't run on behalf of
users with uid < 1000. This makes the test fail when running in some test environments
- eg our hudson jobs internally run as a system user with uid 101.
