Apache Hive 1.2.0 发布数据仓库平台

Hive是一个基于hadoop”>Hadoop的数据仓库平台。通过hive，我们可以方便地进行ETL的工作。hive定义了一个类似于SQL的查询语言：HQL，能够将用户编写的QL转化为相应的Mapreduce程序基于Hadoop执行。

Hive是Facebook 2008年8月刚开源的一个数据仓库框架，其系统目标与 Pig 有相似之处，但它有一些Pig目前还不支持的机制，比如：更丰富的类型系统、更类似SQL的查询语言、Table/Partition元数据的持久化等。

Apache Hive 1.2.0 发布，此版本现已提供下载：https://hive.apache.org/downloads.html。

Hive 1.2.0 发行说明请看这里：https://issues.apache.org/jira/secure/ReleaseNote.jspa?version=12329345&styleName=Text&projectId=12310843。
