The HBase 0.2.0 release includes 291 changes [1]. New features include a richer API, a new ruby irb-based shell, an improved UI, and many improvements to overall stability. To download, visit [4].
HBase 0.2.0 is not backward compatible with HBase 0.1 API (See [2] for an overview of the changes). To migrate your 0.1 era HBase data to 0.2, see the Migration Guide [3] <http://wiki.apache.org/hadoop/Hbase/HowToMigrate>. 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. Thanks to all who contributed to this release.
