Was poking around with PE on a few nodes (I forget the exact
circumstances, need to look back at this), and ran into a case where ~35
regions were left as RIT

Saw entries like this (I think) for each region which was stuck. A
simple `assign` in the shell brought them back, but I need to dig in
some more to understand what went wrong.

Please review 'Upgrading from 1.x to 2.x' in the bundled HBase 2.0.0
Reference Guide before installing or upgrading for a list of
incompatibilities, major changes, and notable new features. 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.
Please take a few minutes to verify the release and vote on releasing it:
