---------------------------------

             Summary: Support multi-homed networks when Kerberos security is enabled
                 Key: HDFS-7935
                 URL: https://issues.apache.org/jira/browse/HDFS-7935
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Arun Suresh
            Assignee: Arun Suresh


Currently, during SASL negotiation stage between ipc Client and Server, The server sends only a single serviceId (curresponding to a single principal) to the client. This is the principal the the server process is logged in as during startup.

It is possible that in a multi-homed network, the server might be associated with more than one principal, and thus severs must provide the clients all possible principals it can use to connect to.
