HBase 0.20.0 is available for download: http://hadoop.apache.org/hbase/releases.html The Release Notes are available here: http://su.pr/2sjrkf This HBase is faster, slimmer, sweeter smelling, and more robust than previous versions. We recommend that all upgrade to this release. HBase 0.20.0 runs on Hadoop 0.20.0. A lot has changed since 0.19.x including configuration fundamentals. Be sure to read the 'Getting Started' documentation: http://hadoop.apache.org/hbase/docs/r0.20.0/api/overview-summary.html#overview_description If you wish to bring your 0.19.x hbase data forward to 0.20.0, you will need to run a migration. See http://wiki.apache.org/hadoop/Hbase/HowToMigrate. First read the overview and then go to the section, 'From 0.19.x to 0.20.x'. Thanks to all who contributed to this release Yours, The HBasistas P.S. 0.20.0 Highlights include: + Much improved performance + Master is no longer SPOF + Rolling restarts -- no need to take down whole cluster updating config. or making minor upgrades + A new, more comprehensive API (The old API is still present but deprecated) + Improved mapreduce connectors updated to suit Hadoop 0.20.0 new mapreduce API + New contrib package with updated Transactional HBase (THBase) and Indexed HBase (ITHBase) as well as a new REST gateway called stargate + And, as they say on the radio, "much, much more".
