Hive表支持中文设置
修改hive的元数据库相关表的属性，元数据库一般是存储在mysql中的，执行如下SQL语句，然后可以在hive中创建带中文的表。
alter table TBLS modify column TBL_NAME varchar(1000) character set utf8;
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;
测试如下
create table if not exists studentno (stuno string comment '学号', stuname1 string comment '姓名') comment '学生信息表';
hive表中字段名支持中文，中文字段使用反引号```括起来。
create table student(`学号` string comment '学号', `姓名` string comment '姓名') comment '学生信息表';
insert into student values('一号','王石');
+-------------+-------------+--+
| student.学号 | student.姓名 |
+-------------+-------------+--+
| 一号 | 王石 |
+-------------+-------------+--+

hive官网相关说明 Table names and column names are case insensitive but SerDe and property names are case sensitive. In Hive 0.12 and earlier, only alphanumeric and underscore characters are allowed in table and column names. In Hive 0.13 and later, column names can contain any Unicode character (see HIVE-6013), however, dot (.) and colon (:) yield errors on querying, so they are disallowed in Hive 1.2.0 (see HIVE-10120). Any column name that is specified within backticks (`) is treated literally. Within a backtick string, use double backticks (``) to represent a backtick character. Backtick quotation also enables the use of reserved keywords for table and column identifiers. To revert to pre-0.13.0 behavior and restrict column names to alphanumeric and underscore characters, set the configuration property hive.support.quoted.identifiers to none. In this configuration, backticked names are interpreted as regular expressions. For details, see Supporting Quoted Identifiers in Column Names. Table and column comments are string literals (single-quoted).
