二.安装Hive服务

1>.如下图所示，点击"yinzhengjie_hadoop"集群的下拉菜单，点击"添加服务"按钮

2>.选择需要安装的Hive服务，并点击"继续"

3>.选择Hive的依赖环境

4>.自定义Hive的角色分配

5>.数据库连接信息设置

6>.自定义Hive在HDFS的数据存储路径，一般情况下默认即可

7>.等待Hive环境安装过程

8>.Hive环境安装完成后，点击"继续"

9>.Hive安装成功

10>.点击"Hive"，进入到Hive的管理界面

11>.依次点击"操作"，"启动"按钮来启动Hive服务

12>.点击启动"启动"会自动去执行Hive相关的命令

13>.等待Hive服务启动过程，首次启动可能会比较耗费时间，因为得去Hdfs集群上创建相应的目录

14>.Hive服务启动完成

15>.查看Hive的实例

16>.查看Hive的WebUI界面

17>.查看HIve的WebUI
