CentOS 6.5 minimal版本MySQL权限问题

报错：Caused by: javax.jdo.JDOFatalDataStoreException: Unable to open a test connection to the given database. JDBC url = jdbc:mysql://192.168.58.141:3306/hive?createDatabaseIfNotExist=true, username = root. Terminating connection pool (set lazyInit to true if you expect to start your database after your app). Original Exception: ------
java.sql.SQLException: null,  message from server: "Host 'master' is not allowed to connect to this MySQL server"
注意：这个是没有添加给master用户权限

①进入mysql：mysql -uroot -p123456
②查看用户权限：use mysql;select user,host,password from mysql.user;
③给master增加所有权限：grant all privileges   on *.* to root@'master' identified by '123456'; 
④注意：一定要检查/etc/profile   环境变量！！！
