impala 建表时报错，不支持中文

1.错误信息

(1366, "Incorrect string value: '\\xE6\\x8E\\x88\\xE6\\x9D\\x83...' for column 'search' at row 1")

（1）查看元数据hive库中的编码格式

（2）更改hive数据库字符集

alter database hive charset utf8;

（3）更改字段类型

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;

在impala 页面报错：1366, "Incorrect string value
