| 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. |
