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.
