CDH建表字符集问题

登陆metadata数据库:

show variables like ‘character_set%‘;

alter database hivemeta default character set latin1;
set character_set_server=latin1;

use hivemeta;
alter table COLUMNS_V2 modify column COMMENT varchar(256) character set utf8;
alter table TABLE_PARAMS modify column PARAM_VALUE varchar(4000) character set utf8;
alter table PARTITION_PARAMS modify column PARAM_VALUE varchar(4000) character set utf8;
alter table PARTITION_KEYS modify column PKEY_COMMENT varchar(4000) character set utf8;
alter table INDEX_PARAMS modify column PARAM_VALUE varchar(4000) character set utf8;

或者:
ALTER TABLE columns_v2 CHANGE COLUMN_NAME COLUMN_NAME VARCHAR(191) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
ALTER TABLE columns_v2 CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
