我正在尝试使用hadoop和hive创建一个docker容器.这是我的Dockerfile

这是hive-site.xml

我能够构建和运行容器.当我执行到容器中时,我可以轻松地执行

root@c29fa91db6a2:/opt/hive/conf# MysqL -uroot -ppassword

但是当我尝试做蜂巢-服务元存储时,我得到了

Caused by: java.sql.sqlException: Unable to open a test connection to the given database. JDBC url = jdbc:MysqL://localhost:3306/Metastore?createDatabaseIfNotExist=true&autoReconnect=true&useSSL=false,username = root. Terminating connection pool (set lazyInit to true if you expect to start your database after your app). Original Exception: ------
com.MysqL.jdbc.exceptions.jdbc4.MysqLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.

在堆栈跟踪的更深处,我看到了

但是,这是root用户拥有的授予

我究竟做错了什么？为了在Docker容器内使用配置单元,我还需要做什么？
另外,我看到MysqL正在运行
