Subject Re: Where to find best documentation for setting up kerberos authentication in 0.20.203.0rc1
Date Mon, 18 Jul 2011 20:26:33 GMT
Hi Issac,

I couldn't find anything specifically for the 0.20.203 release, but CDH3
uses basically the same security code. You could probably follow our
security guide with the 0.20.203 release:
