在Hive中遇到中文乱码的问题，可能是因为Hive默认使用的编码方式不是UTF-8，导致无法正确存储和显示中文字符。解决方法如下：

在创建表时指定字符集为UTF-8：

CREATE TABLE table_name (column1 STRING,column2 INT)ROW FORMAT DELIMITEDFIELDS TERMINATED BY ','STORED AS TEXTFILETBLPROPERTIES ("charset"="utf8");

在Hive配置文件hive-site.xml中设置默认字符集为UTF-8：

<property><name>hive.default.charset</name><value>utf8</value></property>

修改Hive会话的字符集：
