The following page has been changed by DougCutting: http://wiki.apache.org/hadoop/Release1%2e0Requirements ------------------------------------------------------------------------------ ''Owen, you seem to be extending the ["Roadmap"]'s compatibility requirements to RPC protocols, is that right? Clients must be back-compatible with older servers and servers must be back-compatible with older clients. If so, perhaps we should vote on this new policy and update ["Roadmap"] accordingly. We could even start enforcing it before 1.0, so that, e.g., 0.20's protocols would need to be back-compatible with 0.19's but 0.21's would not. --DougCutting'' ''Doug, This is a subtle issue: Here we are talking about new client application code calling old methods on the !FileSystem class (not the RPC methods). This is in addition to the rpc compatibility issue. --!SanjayRadia'' + + ''Sanjay, How does 'new client application code calling old methods on the !FileSystem' differ from our current back-compatibility requirements? --DougCutting'' Question: Does the release number really matter? Should we just keep adding features, improving back-compatibility, etc? Our ["Roadmap"] currently defines what a major release means. Does this need updating? -- !DougCutting
