Be aware that according to our adopted Semantic Versioning guidelines, 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 . There are also CHANGES.md and RELEASENOTES.md in the root directory of the source tarball.
