Subject ANN: The second hbase-0.96-1 release candidate is available for download
Date Thu, 28 Nov 2013 03:57:42 GMT
The second hbase-0.96.1 release candidate is available for download:


The maven artifacts are available here:


The first RC was sunk by:

  HBASE-10053 ProtobufUtil#toMutationNoData interface change causes

We broke hive building against HBase.

137 issues [1] have been fixed since 0.96.0, mostly performance improvement
and bug fixes.

Shall we release this as hbase-0.96.1?  Please vote by December 3rd.
