[ANNOUNCE] Apache HBase 2.0.0-alpha-1 is now available for download

[Stack <st...@duboce.net>]

The HBase team is happy to announce the immediate availability of Apache
HBase 2.0.0-alpha-1.

Apache HBase is an open-source, distributed, versioned, non-relational
database. Apache HBase gives you low latency random access to billions of
rows with millions of columns atop non-specialized hardware. To learn more
about HBase, see https://hbase.apache.org/.

HBase 2.0.0-alpha-1 is our first 2.0.0 release. It is a rough cut ('alpha')
not-for-production preview of what hbase-2.0.0 will look like. It is what we
used to call a 'Developer' release[1] meant mostly for devs and
downstreamers
to test drive and flag us early if we there are issues we’ve missed ahead
of our
hardening the 2.0.0 release.

hbase-2.0.0 includes a fleet of new features that include a new assignment
manager, means for keeping read and write path off-heap, in-memory
compactions ('Accordion'), and more. We have been keeping a running doc on
the state of 2.0.0 here [2]. There is much to do still (see aforementioned
doc).
We would appreciate any feedback especially on the new features whether
comments or bug reports.

The list of features addressed in 2.0.0 so far can be found here [4]. There
are
about 2500. The list of ~500 fixes in 2.0.0 exclusively can be found here
[3].
