Hey, I created branch 4.0.0 from master branch for Phoenix on HBase0.98. The code can work on tip of HBase0.98 & trunk branch but not HBase0.96(only need trivial changes to make it work though) because some "private" Hbase interface changes from release to release. We need a good way to remove all private interface dependencies or convince Hbase folks to make those interface backward compatible.
We thought about to use a shim layer to load either Hbase0.94 or Hbase0.98 dependencies upon different hbase deployment so that we can put this code in master branch. The difficulty is that Phoenix isn't a normal Hbase application. It extensively uses Hbase internals: Coprocessors, WAL, Filters, KeyValue etc which have most incompatible changes between 0.94 & 0.96+. In addition, if more & more people are moving to the modern Hbase code, it's not worth to put significant effort to create such a shim layer. So far all unit tests are passed in 4.0.0 branch. I'll do one more merge to get checkins between 2/8 and today. Moving forward please merge your changes to 4.0.0 in order for it to be used in hbase96+(the bright future). During merge, please don't use deprecated APIs because those APIs mostly internally create a new copy(e.g. Mutation#getFamilyMap) and cause unexpected behaviors if you're thinking to change internal state of an object.
