8 August, 2008: release 0.2.0 available

Includes 291 changes since the 0.1. branch. New features include a richer API, a new ruby irb-based shell, and an improved UI. HBase 0.2.0 is not backward compatible with HBase 0.1 API (See 0.2/0.1 API Changes). To migrate your 0.1 era HBase data to 0.2, see the Migration Guide. HBase 0.2.0 runs on Hadoop 0.17.x. To run 0.2.0 on hadoop 0.18.x, replace the hadoop 0.17.1 jars under $HBASE_HOME/lib with their 0.18.x equivalents and then recompile.

27 June, 2008: release 0.1.3 available

Resolves 20 issues including fixes for a regionserver deadlock, non-splitting in the presence of regions of multiple families under load, unreliable iteration of vintage cells, and improved robustness around crashes. Also includes mild performance improvements. We recommend all upgrade to this latest version.

13 May, 2008: release 0.1.2 available

Resolves 27 issues. Includes critical fixes for 'missing' edits and for unreliable onlining/offlining of tables as well as improvements such as regionservers can now carry twice the regions in same memory. We recommend all upgrade to this latest version.

11 April, 2008: release 0.1.1 available

This release contains bugfixes that enhance the reliability of HBase. See the release notes (above) for details. We recommend all upgrade to this latest version.

27 March, 2008: release 0.1.0 available

This is our first release as a subproject of Hadoop. Previously, HBase was a Hadoop contrib project. HBase 0.1.0 is substantially our last release, the HBase that was bundled under Hadoop 0.16.0 contrib but with lots of fixes to improve stability. See the release notes (above) for details. We recommend all upgrade to this latest version.

Note
An HBase install now stands apart from Hadoop. To accomodate, base configuration has changed in that hbase.rootdir must now include a fully-qualify path to your HBase directory: e.g. hdfs://example.org:9000/hbase. Read the Getting Started notes to learn more.

HBase 'promoted' to Hadoop Sub-project

02/11/2008: HBase originally incubated as a contribution to Hadoop. As of the start of February, near-contemporaneous with Hadoops' becoming a TLP Apache project, HBase was 'promoted' to become a subproject of Hadoop. Hadoop 0.16.0 was the last Hadoop release to carry HBase and is, as of this writing, the most recent official HBase release (see under the contrib subdirectory of the Hadoop release).

Going forward, all future HBase releases will be hosted on this page. A 0.1 branch has already been made and releases made on this branch will be fixes to for the release 0.16.0 release of HBase. The first 'standalone' HBase release will be 0.1.0 and would roughly equate to the HBase that would have been shipped in Hadoop 0.16.1, if HBase were still hosted inside Hadoop.
