I am using CDH4 (2.0.0-mr1-cdh4.1.2) vm running on my mbp.

I was trying to invoke a remote method in the ClientProtocol via RPC,
however I am getting this exception.

2013-01-29 11:20:45,810 ERROR
org.apache.hadoop.security.UserGroupInformation:

I could understand if the Server's ClientProtocol has version number
"60" or something else, but how could it has a version number of "1"?

Thanks.

Please take this up in CDH mailing list. Most likely you are using client
that is not from 2.0 release of Hadoop.
