User Authentication Using Kerberos

Hi All,

   i am working on hadoop security wherein in the first step to
authenticate users,Kerberos authentication protocol was used.
Is it wise using Kerberos (version in C) or otherwise have to look
for Java Kerberos version 1.1 for hadoop security framework??

Thanks
Regards
Suji

Look at the UserGroupInformation class in subversion trunk. It uses
Java's JAAS interface to authenticate the user using Kerberos. The RPC
connections are authenticated with Kerberos or delegation tokens that
are generated by the NameNode or JobTracker.
