Hive学习（使用mysql存储元数据）

2019年6月8日 317次阅读 来源: tonyemail_st

Hive2.3版本的安装

参考文章：

注意事项：

下载的mysql-connector-java-5.1.43.tar.gz，需要解压后再移动到$HIVE_HOME/lib中去。

报错解决：
hive> show tables;

解决方法：

[root@hive apache-hive-2.3.0-bin]# hostname
hive
[root@hive apache-hive-2.3.0-bin]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
1.1.1.36 hive
[root@hive apache-hive-2.3.0-bin]# ip a
