                 Key: HADOOP-7215
                 URL: https://issues.apache.org/jira/browse/HADOOP-7215
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
            Reporter: Suresh Srinivas
            Assignee: Suresh Srinivas
             Fix For: 0.20.203.0, 0.20.204.0, 0.23.0


HDFS-7104 introduced a change where RPC server matches client's hostname with 
the hostname specified in the client's Kerberos principal name. RPC client 
binds the socket to a random local address, which might not match the hostname 
specified in the principal name. This results authorization failure of the 
client at the server.
