Hey Brock,
I've seen a similar problem at another site. They were able to
solve this by upgrading their version of OpenAFS. Is that an
option for you?
It might be, I see we are running 1.4.8 and they have 1.5 out, not
sure what our cell is running and compatibility, good to know.

Ran into an issue with running hadoop on a cluster that also has
AFS installed. When a user ssh's in they get an 'extra' group
id, I think it is called a 'pag',
Problem is when you try to start hadoop from a shell that has a
pag, one of the checks in newer versions stops because there is no
group name to go with the gid,
as an example from the 'groups' command:
[bro...@nyx-login1 ~]$ groups
cacstaff vasp stata charmm amber8 siesta eecs587f06 nolimit gti
hyades adina chemkinpro coe molpro aces2 helios mcnp5 matlab id:
cannot find name for group ID 1093742985
1093742985
If you ssh to the machine its self using ssh keys, the pag is not
created, which our current work around, but is kinda kludgy,
If you need more information let me know.
