The fifth hbase 0.92.0 release candidate is available for download: http://people.apache.org/~stack/hbase-0.92.0-candidate-4/
I've posted a secure and an insecure tarball built by jenkins. This RC bundles hadoop 1.0.0 and zookeeper 3.4.2. As said previous, HBase 0.92.0 includes a boat-load of new features including coprocessors, security, a new (self-migrating) file format, distributed log splitting, etc. There's been > 670 fixes since 0.90. See the list here: http://su.pr/1VZzl5 See the hbase manual for the low-down on what hadoop version this release will run on: http://hbase.apache.org/book.html#hadoop There is no migration necessary. A shutdown and restart after putting in place the new HBase should be all thats involved (A rolling restart from 0.90.x to 0.92.0 will not work). That said, once you have moved to 0.92.x, there is no going back to 0.90.x after the transition has been made. Should we release this candidate as hbase 0.92.0? Vote +1/-1. Lets make this evaluation period short since RC3 almost made it and this RC differs but little. Lets say the vote closes Friday, January 20th, 2012. Yours, The HBasistas
