hbase(main):002:0> create 'test_table','f'

　语法：　create table name , column family

　　　　test_table  是HBase的数据表名，f是列簇

　　为了后续的编程，我这里直接先手动创建最简单的hbase数据表。在代码里可以修改。

Oozie安装部署

不多说，直接上干货！首先，大家先去看我这篇博客。对于Oozie的安装有一个全新的认识。 Oozie安装的说明我这里呢，本篇博文定位于手动来安装Oozie，同时避免Apache版本的繁琐编译安装，直接使用CDH版本，已经编译好的oozie-4.1.0-cdh5.5.4.tar.gz。如果，你要使用Apache版本的话，则需要自己去编译吧！ Apache版本只有1.7M。CDH（已经帮我们编译好了）有1.0G。第一大步：oozie-4.1.0-cdh5.5.4.tar.gz的下载 http://archive.cloudera.com/cdh5/cdh/5/ 当然，你这里也可以不像我这里，本地下载好，也可以在线下载。第二大步：ApacheOozie 4.1.0编译的参考官方文档（这个大家去做吧） http://oozie.apache.org/docs/4.1.0/DG_QuickStart.html#Building_Oozie 上面是官网要求，至少的！但是呢，现在，我建议大家，如下。使用的环境是：Hadoop-2.6.0 Oozie 4.2.0 ...
