Be aware that according to our adopted Semantic Versioning guidelines[1], we've allow ourselves to make breaking changes in this major version release. For example, Coprocessors will need to be recast to fit more constrained CP APIs and a rolling upgrade of an hbase-1.x install to hbase-2.x without downtime is (currently) not possible. That said, a bunch of effort has been expended mitigating differences; a hbase-1.x client can perform DML against an hbase-2 cluster. For the full list of ~6k issues addressed, see [2]. There are also CHANGES.md and RELEASENOTES.md in the root directory of the source tarball.
