二.创建Hive的元数据信息

1>.MySQL 8.x以上版本需要确认的配置文件密码策略

[root@hdp101.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/my.cnf
[mysqld]
validate_password.policy=LOW
innodb_file_format=BARRACUDA
innodb_large_prefix=true
innodb_default_row_format=DYNAMIC
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
[root@hdp101.yinzhengjie.org.cn ~]#
[root@hdp101.yinzhengjie.org.cn ~]# grep validate_password.policy /etc/my.cnf
validate_password.policy=LOW
[root@hdp101.yinzhengjie.org.cn ~]# 

2>.MySQL授权用户

[root@hdp101.yinzhengjie.org.cn ~]# mysql -uroot -pyinzhengjie
mysql: [Warning] Using a password on the command line interface can be insecure.

Bye
[root@hdp101.yinzhengjie.org.cn ~]#
[root@hdp101.yinzhengjie.org.cn ~]# 

2>.测试MySQL授权用户的权限

[root@hdp101.yinzhengjie.org.cn ~]# mysql -uhive -pyinzhengjie -h 172.200.1.101

三.基于Ambari的WebUI部署HBase服务

1>.启动服务安装向导

2>.选择要添加的hive服务和Tez(如果不勾选Tez的话Ambari也会自动帮咱们勾选的，Tez服务是HDP要求咱们强制安装的~)

3>.配置Hive的源数据库信息

4>.勾选需要安装hive的客户端对应的主机

5>.Tez界面不做任何的配置修改，点击"HIVE"

6>.配置数据库的相关信息

7>.测试连接数据库时报错啦

resource_management.core.exceptions.Fail: Check db_connection_check was unsuccessful. Exit code: . Message: The MySQL JDBC driver has not been set. Please ensure that you have executed 'ambari-server setup --jdbc-db=mysql --jdbc-driver=/path/to/jdbc_driver'.

　　根据报错日志的提示，需要我们手动设置MySQL驱动，具体操作如下:
　　　　[root@hdp101.yinzhengjie.org.cn ~]# ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar

8>.配置MySQL数据库连接信息并测试连接 

　　测试连接数据库失败时，请仔细检查以下两项:
　　　　(1)测试连接MySQL的用户是否有权限登录;
　　　　(2)确认填写的MySQL配置信息是否有错误，尤其是MySQL的密码(因为密码内容被隐藏了不易被发现);

9>.暂时忽略警告信息，点击"PROCEED ANYWAY"，即无论如何都继续

10>.Review之前的配置信息，确认无误后点击部署,即"DEPLOY"

11>.正在初始化任务

12>.等待Hive 客户端组件安装完毕

13>.等待启动HiveServer2服务，之后会安装Tez服务

14>.等待所有组件安装成功,点击下一步

15>.Hive服务安装成功

16>.安装Hive成功后会自动跳转到主界面
