Subject VOTE: hbase-0.95RC1, the second "Development" Series Release is available [WAS -> VOTE: hbase-0.95.0RC0, the first "Developer Release" release candidate is available for download and vote]
Date Wed, 03 Apr 2013 05:12:05 GMT
Here is the second 0.95.0 release candidate.  Should we put this out as
0.95.0?  Please
vote by friday, April 5th.

See the refguide [1] for definition of what a "Development" Series Release
is (or read below where we call it a 'developer release").  In short, it is
a preview release, not for production, put out early so us devs start
getting feedback the sooner.

The release is available here:


Issues fixed in this release are available here:


...including a fix for HBASE-8242, the issue that sunk the first release
