任何人都可以幫我解決這個問題嗎？我正在試圖將mysql結果導出到mysql，但是我遇到了拒絕訪問用戶的問題。用戶名和密碼絕對正確。SQLException。導出爲mysql時使用PIG時的JDBC錯誤
這是我的PIG腳本：
REGISTER 'hdfs:///home/mysql-connector-java-3.1.14-bin.jar';
REGISTER 'hdfs:///home/piggybank-0.12.0.jar';
test = LOAD '/home/data.csv' USING PigStorage(',') AS (nom1:chararray, nom2:chararray, nom3:float, nom4:chararray);
processedtest = FOREACH test GENERATE nom1, nom2, nom3, nom4;
STORE processedtest INTO 'table' USING org.apache.pig.piggybank.storage.DBStorage('com.mysql.jdbc.Driver', 'jdbc:mysql://localhost/test', 'root', 'root', 'INSERT INTO table (nom1, nom2, nom3, nom4) VALUES (?, ?, ?, ?)');
這是從日誌文件中的錯誤：

這是我的mysql的狀態：我可以向你保證，我用的密碼「根」來訪問它：
Connection id: 6
Current database:
Current user: [email protected]
SSL: Not in use
Using delimiter: ;
Server version: 5.5.37 MySQL Community Server (GPL)
Protocol version: 10
Connection: localhost via TCP/IP
Server characterset: latin1
Db characterset: latin1
Client characterset: latin1
Conn. characterset: latin1
TCP port: 3306
Uptime: 5 hours 46 min 49 sec
我仍然是一個新手，所以建議我任何其他方法是有益的，更有效的時候導出到MySQL。
