Apache HBase 3.0.0-beta-1 is now available for download

The HBase team is happy to announce the immediate availability of HBase
3.0.0-beta-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 3.0.0-beta-1 is the first beta release in the HBase 3.x line, which is
the fifth release of our next major release line. It includes roughly 4000+
resolved issues since 2.0.0.

A beta release usually means that there will be no new big feature for 3.0.0
release line any more, and the release is much stabler than the alpha releases
before, as we have passed several 1B ITBLL runs and one 10B ITBLL run. So you
can try it in more critical environments, but still need to use it
with caution, 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
A new file system based replication peer storage
Use hbase table instead of zookeeper for tracking hbase replication queue

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
Yield SCP and TRSP to improve MTTR when restarting large cluster
