Subject [ANN] HBase 0.20.0 available for download
Date Wed, 09 Sep 2009 00:08:46 GMT
HBase 0.20.0 is available for download:


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'

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
