Re: Proposal: abandon protocol translator layer for cluster-internal RPCs

Wire compatibility in hdfs private protocols between different components is also important for rolling upgrades. We do want to support upgrading different components of a cluster independent of each other and wire compatibility is one of the essential prerequisites. Therefore, even if some

Re: Proposal: abandon protocol translator layer for cluster-internal RPCs

I think what we are talking about here is removing some of the extra layers of abstraction in java. The wire protocol used will be identical in either case. It is just that we would have to use the Protocol Buffer Builder APIs instead of wrapping them with our own custom getters/setters. I
