The HBase team is happy to announce the immediate availability of HBase
3.0.0-alpha-3.

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 3.0.0-alpha-3 is the third alpha release in the HBase 3.x line, which is
the third release of our next major release line. It includes roughly 3500+
resolved issues since 2.0.0.

Notice that this is not a production ready release. It is used to let our
users try and test the new major release, to get feedback before the final GA
release is out. So please do NOT use it in production. Just try it and report
back everything you find unusual.

Notable new features include:
Synchronous Replication
OpenTelemetry Tracing
Distributed MOB Compaction
Backup and Restore
Decouple region replication and general replication framework, and
also make region replication can work when SKIP_WAL is used

For other important changes:
We do not support hadoop 2.x any more
Move RSGroup balancer to core
Reimplement sync client on async client
CPEPs on shaded proto
Move the logging framework from log4j to log4j2
