| 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. |

| NEW FEATURES |
| HADOOP-1768 FS command using Hadoop FsShell operations |
| (Edward Yoon via Stack) |
| HADOOP-1784 Delete: Fix scanners and gets so they work properly in presence |
| of deletes. Added a deleteAll to remove all cells equal to or |

| The old shell syntax has been replaced by HQL, a small SQL-like |
| set of operators, for creating, altering, dropping, inserting, |
| deleting, and selecting, etc., data in hbase. |
