ANN: The third hbase 0.90.0 release candidate is available for download
The third hbase 0.90.0 release candidate is available for download:
http://people.apache.org/~stack/hbase-0.90.0-candidate-2/
HBase 0.90.0 is the major HBase release that follows 0.20.0 and the
fruit of the 0.89.x development release series we've been running of
late.
Over 1k issues have been closed since 0.20.0. Release notes are
available here: http://su.pr/8LbgvK.
HBase 0.90.0 runs on Hadoop 0.20.x. It does not currently run on
Hadoop 0.21.0 nor on Hadoop TRUNK. HBase will lose data unless it is
running on an Hadoop HDFS 0.20.x that has a durable sync. Currently
only the branch-0.20-append branch [1] has this attribute (See
CHANGES.txt [3] in branch-0.20-append to see the list of patches
involved adding an append). No official releases have been made from
this branch as yet so you will have to build your own Hadoop from the
tip of this branch, OR install Cloudera's CDH3 [2] (Its currently in
beta). CDH3b2 or CDHb3 have the 0.20-append patches needed to add a
durable sync. If using CDH, be sure to replace the hadoop jars that
are bundled with HBase with those from your CDH distribution.
There is no migration necessary. Your data written with HBase 0.20.x
(or with HBase 0.89.x) is readable by HBase 0.90.0. A shutdown and
restart after putting in place the new HBase should be all thats
involved. That said, once done, there is no going back to 0.20.x once
the transition has been made. HBase 0.90.0 and HBase 0.89.x write
region names differently in the filesystem. Rolling restart from
0.20.x or 0.89.x to 0.90.0RC1 will not work.
Should we release this candidate as hbase 0.90.0? Take it for a spin.
Check out the doc., etc. Vote +1/-1 by January 3rd, 2011.
Yours,
The HBasistas
P.S. For why the version 0.90 and whats new in HBase 0.90, see slides
4-10 in this deck [4]

I am out of town, but this is truely the best release of HBase yet! I
have run other versions of this and things are just excellent.
Please download and give it a spin! Even if it's just on a small test
cluster, for a day, whatever!

-1 for the following bugs:
HBASE-3403 - Region orphaned if RS fails during split (stack and I working
on it)
HBASE-3344 - Master aborts after RPC to server that was shutting down (stack
fixed)
But I feel like we're getting close!
