The first 0.2.0 release candidate is available for download:
http://people.apache.org/~stack/hbase-0.2.0-candidate-1/
Please take this release candidate for a spin. Check the documentation,
that unit tests all complete on your platform, etc.
Should we release this candidate as hbase 0.2.0? Vote yes or no before
Friday, July 25th.
Release 0.2.0 has over 240 issues resolved [1] since the branch for 0.1
hbase was made. Be warned that hbase 0.2.0 is not backward compatible
with the hbase 0.1 API. See [2] Izaak Rubins' notes on the high-level API
differences between 0.1 and 0.2. For notes on how to migrate your 0.1 era
hbase data to 0.2, see Izaak's migration guide [3].
Yours,
The HBase Team
