Hive创建数据库时报错【Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. MetaException】（已解决）

Hive创建数据库时报错【Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. MetaException】（已解决）

版本信息

• hive : 2.3.4
• mysql: 5.7.25
• mysql驱动包：5.11
• 系统：centos6.5

前置操作

输入show databases;无异常，输入create database db_test;出现报错原因

解决思路

hive -hiveconf hive.root.logger=DEBUG,console

使用debug模式启动，重现bug，启动无异常，输入create database db_test;出现下面报错，推断应该是编码问题，mysql默认是latin1编码

解决办法

• 实现创建好hive的数据库并指定编码格式为utf8

  create database hivedb charset=utf8;
  

• 数据库名为hive-site.sh配置文件中的数据库连接中的配置

• 重启hive，解决
