Apache HBase Files

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

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 is the first GA release for the 3.x release line, which includes roughly 5000+ resolved issues since 2.0.0.

Notice that, starting from 3.0.0, 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
