[DISCUSS] Drop support for HBase 0.94 from new versions

[Gary Helmling]

Hi all,

As we continue adding new features to Tephra, the cost of continuing to support HBase 0.94 is becoming apparent.  Some features cannot easily be added to HBase 0.94 (specifically TEPHRA-91 -- having clients perform normal delete operations), due to some structural differences around the server-side handling in HBase 0.94 vs. 0.96+.

So, in order to free up development of new features, I propose that we drop support for HBase 0.94 in new major Tephra releases.  This means that from Tephra 0.5.0 on, HBase 0.94 would no longer be supported.  HBase 0.94 users could still continue to use Tephra 0.4.x, and if there is actually demand, we could continue to do bugfix releases along this line.

Is anyone currently using Tephra on HBase 0.94?  Or does anyone object to this plan?  Since we have limited resources, I would prefer to focus those on features that we need and supporting new HBase versions, such as 1.0.
