Gokul Soundararajan created HADOOP-11823:
--------------------------------------------

             Summary: Checking for Verifier in RPC Denied Reply
                 Key: HADOOP-11823

             Project: Hadoop Common
          Issue Type: Bug
          Components: nfs
    Affects Versions: 2.6.0
            Reporter: Gokul Soundararajan

Hi,

There is a bug in the way hadoop-nfs parses the reply for a RPC denied message. Specifically, this happens in RpcDeniedReply.java line #50.
When RPC returns a denied reply, the code should not check for a verifier. It is a bug as it doesn't match the RPC protocol. (See Page 33 from NFS Illustrated book). 

I would be happy to submit the patch but I need some help to commit into mainline. I haven't committed into Hadoop yet.

Thanks,

Gokul
