I have setup a small cluster running 0.20.203.0rc1. I want to enable Kerberos authentication to restrict access to the hadoop filesystem based on the authenticated username. I want this to use our existing Kerberos servers.
Where can I find the best documentation for doing this? I've done some searching in regards to this issue, but didn't find much.
Would there be any improvements if I switch to a different release of hadoop? My current, possibly wrong, understanding is that 0.21 does not include Kerberos support.
Thanks for any help!
