hive表注释中文乱码问题

1.修改hive存储在mysql里的元数据相关信息

a. 修改字段注释字符集

alter table COLUMNS_V2 modify columnCOMMENT varchar(256) character set utf8;

b. 修改表注释字符集

alter table TABLE_PARAMS modifycolumn PARAM_VALUE varchar(4000) character set utf8;

c. 修改分区表参数，以支持分区键能够用中文表示

alter table PARTITION_PARAMS modifycolumn PARAM_VALUE varchar(4000) character set utf8;

alter table PARTITION_KEYS modifycolumn PKEY_COMMENT varchar(4000) character set utf8;

d. 修改索引注解

alter table INDEX_PARAMS modifycolumn PARAM_VALUE varchar(4000) character set utf8;

2. 修改hive-site.xml

vi hive-site.xml

<property>

   <name>javax.jdo.option.ConnectionURL</name>

   <value>jdbc:mysql://IP:3306/hive?useSSL=false&amp;createDatabaseIfNotExist=true&amp;characterEncoding=UTF-8</value>
   
</property>

3. 重建表结构
