> Classes/Methods moved:
> * HBASE-19425 (and subtasks) Put/Delete/Increment/Append
> * HBASE-19627 (and subtasks) Cell & Impl
> * HBASE-18978 (and subtasks) Async/Table
> * HBASE-18805 (and subtasks) Async/Admin
> * HBASE-14996 (and subtasks) Lots of misc changes
> * HBASE-13197 (and subtasks) Connection
> * HBASE-13844 KeyValue -> CellUtil
> * Maybe HBASE-19950 is worth calling out? Not really an upgrade issue though, but I know the old behavior of SCVF changed in a surprising way for the YARN ATS folks, when they were previously relying on what ended up being a bug.
> Could be mitigated by having a compatibility report, but would benefit from narrative messaging.
> Almost definitely need a blanket reminder that some deprecated APIs went away.

> My intention was for both of these to be handled by this blurb:

> +[[upgrade2.0.public.api]]
> +.Multiple breaking changes to source and binary compatibility for client API
> +The Java client API for HBase has a number of changes that break both source and binary compatibility for details see the Compatibility Check Report for the release you'll be upgrading to.

> I figure once we get an appendix that provides guidance on migrating an application from 1.x to 2.x we can also link to it.

> Get an appendix in place and then update the upgrade section as needed to draw attention to it.
