[ANNOUNCE] Apache HBase 2.0.0 is now available for download
The HBase team is happy to announce the immediate availability of Apache
HBase 2.0.0.
Apache HBase™ is the Hadoop database, a distributed, scalable, big data
store.
To learn more about HBase, see https://hbase.apache.org/.
HBase 2.0.0 is our second major release, the first release off the HBase
2.0 line.
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 notable
incompatibilities, major
changes, and features including a new Region assignment manager ("AMv2"),
a means for configuring the read and/or write path to run off-heap, and an
optional In-Memory Compaction ("IMC", A.K.A "Accordion") facility.
According to our adopted Semantic Versioning guidelines[2], we allowed
ourselves make breaking changes in this major version release. For
example, Coprocessors will need to be recast to fit more constrained APIs
and
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 the
differences; a hbase-1.x client can perform DML against an hbase-2 cluster.
A
bundled compatibility report showing difference from 1.2.6 may be of help
[3].
For the complete list of fixes and improvements, see the included
`CHANGES.md` (or online at [1]) and `RELEASENOTES.md`.

The moderator for the Apache Announce mailing list (and our Sean) noticed
that the links to the .asc and .sha512 files in my original posting were
incorrect. These files do not make it out to Apache mirrors. They remain at
home on www.apache.org/dist.
I corrected the pointers and re-submitted the amended announce to
announce@apache.org. It appears here:
https://s.apache.org/hbase-2.0.0-ANNOUNCE. Please use this ANNOUNCE in
place of my original going forward.
Thanks,
Your 2.0.0 RM.
