character_set_database   需要设置成“latin1”

修改数据库编码：

mysql> set  character_set_database =latin1;
Query OK, 0 rows affected (0.00 sec)

mysql> show variables like '%char%';

+--------------------------+----------------------------+
8 rows in set (0.00 sec)

为了支持Hive建表时插入中文注释 需要在MySQL中做如下设置：

use hive;

//修改字段注释字符集
alter table COLUMNS_V2 modify column COMMENT varchar(256) character set utf8;
//修改表注释字符集
alter table TABLE_PARAMS modify column PARAM_VALUE varchar(4000) character set utf8;
//修改分区注释字符集
alter table PARTITION_KEYS modify column PKEY_COMMENT varchar(4000) character set utf8;

再次执行建表语句，成功！！！

    > (
    > page_id bigint comment '页面ID',
    > page_name string comment '页面名称',
    > page_url string comment '页面URL'

    > comment '页面视图'
    > partitioned by (ds string comment '当前时间，用于分区字段')
