Hive中⽂注释乱码--解决

my.cnf 文件配置

• 切换mysql管理用户
• vi /etc/my.cnf [mysqld]之后添加如下内容

[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'
init_connect='SET NAMES utf8'
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake

Hive元数据库修改

#切换hive的元数据库
mysql> use data_hive;
#修改表字段和表注解
mysql> alter table COLUMNS_V2 modify column COMMENT varchar(256) character set utf
8;
mysql> alter table TABLE_PARAMS modify column PARAM_VALUE varchar(4000) character
set utf8;
#修改分区字段注解
mysql> alter table PARTITION_PARAMS modify column PARAM_VALUE varchar(4000) charac
ter set utf8;
mysql> alter table PARTITION_KEYS modify column PKEY_COMMENT varchar(4000) charact
er set utf8;
#修改索引注解
