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 fails if run as a userid < 1000

> 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.
