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 The full list of issues and release notes can be found here: CHANGELOG: https://downloads.apache.org/hbase/3.0.0-beta-2/CHANGES.md RELEASENOTES: https://downloads.apache.org/hbase/3.0.0-beta-2/RELEASENOTES.md or via our issue tracker: https://issues.apache.org/jira/projects/HBASE/versions/12353291 https://issues.apache.org/jira/projects/HBASE/versions/12351845 https://issues.apache.org/jira/projects/HBASE/versions/12350942 https://issues.apache.org/jira/projects/HBASE/versions/12350250 https://issues.apache.org/jira/projects/HBASE/versions/12332342 https://issues.apache.org/jira/projects/HBASE/versions/12354055 To download please follow the links and instructions on our website: https://hbase.apache.org/downloads.html Questions, comments, and problems are always welcome at: [email protected] [email protected] [email protected] Thanks to all who contributed and made this release possible.
