在hive重新进行初始化时，出现以上错误。

Schema initialization FAILED! Metastore state would be inconsistent !!
架构初始化失败！ Metastore状态会不一致!!

在出现以上错误时，解决方法如下

1. 删除metastore_db文件

2. 删除数据库中对应的database

   
           javax.jdo.option.ConnectionURL
           jdbc:mysql://node1:3306/hive_new?createDatabaseIfNotExist=true
   
   

在配置文件中如果配置的数据库名字是：hive_new，则将该数据库删除即可。

进行以上操作后，进行重新初始化

 schematool -dbType mysql -initSchema
