hive安装遇到的问题

apt-get install mysql-server

mysql -u root -p

create user 'hive'@'localhost' identified by 'hive';

grant all on hive.* to 'hive'@'localhost';

 解压hive安装文件，进入conf目录

将jdbc驱动放入hive/lib下

复制一份hive-env.sh 和hive-site.xml文件

修改 hive-site.xml配置文件内容。

在启动hive是没有问题。

使用hive命令：show tables；是会出现以下错误。

hive> show tables
    > ;

 查遍了google和baidu没有找到解决办法。最后是改了conf下的hive-site.xml文件中的数据库连接。

把ip改成了localhost。再启动hive就对了。。。
