http://people.apache.org/~stack/hbase-0.20.0-candidate-3/

463 issues have been addressed since the 0.19 branch. Release notes are available here: http://su.pr/18zcEO http://tinyurl.com/8xmyx9.

HBase 0.20.0 runs on Hadoop 0.20.0. A bunch has changed since 0.19.x including configuration fundamentals. Be sure to read the 'Getting Started' documentation in 0.20.0 available here: http://su.pr/3HMI0W

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'.

Should we release this candidate as hbase 0.20.0? Please vote +1/-1 by Tuesday, September 8th.

Yours, The HBasistas
