  ==== Discussion on Manual vs Automated Scheme for Versioning ====
  A manual scheme is too messy and cumbersome. An automated scheme a la Protocol Buffers,
Etch, Thrift, Hessian should be used.
+ For 1.0 we should not switch Hadoop's RPC mechanism. That is a good change to target for
2.0, when the RPC landscape is clearer.  We have very specific performance needs for RPC that
these other mechanisms do not yet support. -DougCutting''
  === RPC server that's forward-friendly ===
     * RPC mechanism should be able to detect and throw exception on new methods that old
servers clearly don't implement.
