Release Apache HBase 3.0.0-beta-2 is now available for download · apache/hbase

The HBase team is happy to announce the immediate availability of HBase
3.0.0-beta-2.

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-2 is the second beta release in the HBase 3.x line, which is
the sixth release of our next major release line. It includes roughly 5000+
resolved issues since 2.0.0.

3.0.0-beta-2 is the last beta release before the final 3.0.0 release. We have
passed several round of 10B ITBLL runs so the core features should be
considered stable enough for production use. And we will cut the final 3.0.0
release soon.

Notice that, starting from 3.0.0-beta-2, we have moved up to JDK17. JDK8 and
JDK11 support have been dropped.

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
