      Description

      When an older Hadoop version tries to contact a newer Hadoop version across an IPC protocol version bump, the client currently just gets a non-useful error message like "EOFException".

      Instead, the IPC server code can speak just enough of prior IPC protocols to send back a "fatal" message indicating the version mismatch.
