二、解决方法
1、进入mysql执行：show create database metastore;  发现默认是utf8类型    

mysql> show create database metastore;
+----------+---------------------------------------------------------------+
| Database | Create Database                                               |
+----------+---------------------------------------------------------------+
| metastore     | CREATE DATABASE `metastore` /*!40100 DEFAULT CHARACTER SET utf8 */ |
+----------+---------------------------------------------------------------+

2、在mysql中修改metastore元数据属性

mysql> use metastore;

mysql> alter table COLUMNS_V2 modify column COMMENT varchar(256) character set utf8;

mysql> alter table TABLE_PARAMS modify column PARAM_VALUE varchar(4000) character set utf8;

mysql> alter table PARTITION_PARAMS  modify column PARAM_VALUE varchar(4000) character set utf8;

mysql> alter table PARTITION_KEYS  modify column PKEY_COMMENT varchar(4000) character set utf8;

mysql> alter table  INDEX_PARAMS  modify column PARAM_VALUE  varchar(4000) character set utf8;
4、重新建表，再desc查看，此时中文注释显示正常。(show create table显示也是正常的)
