4019 Release 0.16.0
4021 2008/02/04 HBase is now a subproject of Hadoop. The first HBase release as
4022 a subproject will be release 0.1.0 which will be equivalent to
4023 the version of HBase included in Hadoop 0.16.0. In order to
4024 accomplish this, the HBase portion of HBASE-288 (formerly
4025 HADOOP-1398) has been backed out. Once 0.1.0 is frozen (depending
4026 mostly on changes to infrastructure due to becoming a sub project
4027 instead of a contrib project), this patch will re-appear on HBase
4028 trunk.
