Dear Wiki user, You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.
The following page has been changed by DougCutting: http://wiki.apache.org/hadoop/Release1%2e0Requirements ------------------------------------------------------------------------------ ==== 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.
