The HBase team is happy to announce the immediate availability of HBase 3.0.0-alpha-4.
Apache HBaseâ„¢ 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-4 is the fourth alpha release in the HBase 3.x line, which is the fourth release of our next major release line. It includes roughly 4000+ resolved issues since 2.0.0. HBase 3.0.0-alpha-4 release will mark the final alpha version for the HBase 3.x line. This indicates that the major features for 3.x have been finalized. The subsequent release, 3.0.0-beta-1, will prioritize improving stability and cleaning up the API. 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 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 The full list of issues and release notes can be found here: CHANGELOG: https://downloads.apache.org/hbase/3.0.0-alpha-4/CHANGES.md RELEASENOTES: https://downloads.apache.org/hbase/3.0.0-alpha-4/RELEASENOTES.md or via our issue tracker: 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 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: d...@hbase.apache.org u...@hbase.apache.org user-zh@hbase.apache.org Thanks to all who contributed and made this release possible.
