MySQL с ульем

Question

Когда я пытаюсь подключиться MySQL удаленно (из DataNode в Hadoop-2.5.1 кластере) с ульем он бросает errot:

Caused by: java.sql.SQLException: Unable to open a test connection to the given database. JDBC url = jdbc:mysql://192.168.4.43:3306/metastore ? createDatabaseIfNotExist=true, username = root. Terminating connection pool. Original Exception: ------

Answer 1

Вы должны создать новую MySQL пользователя для Рави из командной строки, как показано ниже:

CREATE USER 'ravi'@'localhost' IDENTIFIED BY 'password'; 
GRANT ALL PRIVILEGES ON *.* TO 'ravi'@'localhost' WITH GRANT OPTION; 
CREATE USER 'ravi'@'%' IDENTIFIED BY 'password'; 
GRANT ALL PRIVILEGES ON *.* TO 'ravi'@'%' WITH GRANT OPTION; 

Изменить соответствующие значения, как в вашей среде, и повторите запрос с улья.
