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. | |

to a single row at a time) | |
51. HADOOP-1528 HClient for multiple tables (phase 1) (James Kennedy & JimK) | |
52. HADOOP-1528 HClient for multiple tables (phase 2) all HBase client side code | |
