我面临着这个我无法解决的问题。我正在用mysql集成编写javaspark代码。我可以看出这有一个小补丁。

package JavaSpark.Javs.SQL;

import java.util.Properties;

import org.apache.spark.sql.Dataset;
import org.apache.spark.sql.Row;
import org.apache.spark.sql.SparkSession;

public class sparkSqlMysql {

private static final org.apache.log4j.Logger LOGGER = org.apache.log4j.Logger.getLogger(sparkSqlMysql.class);

private static final String MYSQL_CONNECTION_URL = "jdbc:mysql://localhost:3306/BCG";
private static final String MYSQL_USERNAME = "root";
private static final String MYSQL_PWD = "mypassword";

private static final SparkSession sparkSession =
        SparkSession.builder().master("local[*]").appName("Spark2JdbcDs").getOrCreate();

public static void main(String[] args) {
    //JDBC connection properties
    final Properties connectionProperties = new Properties();
    connectionProperties.put("user", MYSQL_USERNAME);
    connectionProperties.put("password", MYSQL_PWD);
    connectionProperties.put("driver", "com.mysql.jdbc.Driver");
    final String dbTable =
            "select * from testLoad";
     // Load MySQL query result as Dataset
    Dataset<Row> jdbcDF =
            sparkSession.read()
                    .jdbc(MYSQL_CONNECTION_URL, dbTable, connectionProperties);
  }
}

当我执行时，这给了我一个错误
sql语法有错误；在com.mysql.cj.jdbc.exceptions.sqlerror.createsqlexception（sqlerror）的第1行中，检查与您的mysql服务器版本对应的手册，以获取在“”附近使用的正确语法。java:120)
有什么问题，我该怎么解决？
