-Release 0.16.0
-
- 2008/02/04 HBase is now a subproject of Hadoop. The first HBase release as
- a subproject will be release 0.1.0 which will be equivalent to
- the version of HBase included in Hadoop 0.16.0. In order to
- accomplish this, the HBase portion of HBASE-288 (formerly
- HADOOP-1398) has been backed out. Once 0.1.0 is frozen (depending
- mostly on changes to infrastructure due to becoming a sub project
- instead of a contrib project), this patch will re-appear on HBase
- trunk.
