用JDBC连接Impala

1.下载所需要的架包

     http://download.csdn.net/detail/qq_36611929/9894733

本人导入所有架包出错，所以就删掉了slf4j-api-1.5.11.jar、slf4j-log4j12-1.5.11.jar、log4j-1.2.14.jar三个包

2.编写JDBC,并测试是否连接成功

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

public class ImpalaDao {
private static String DRIVER = "com.cloudera.impala.jdbc41.Driver";
private static String URL = "jdbc:impala://192.168.0.111:21050/DataBaseName";
public static void main(String[] args) {
Connection conn = null;
ResultSet rs = null;
PreparedStatement pst = null;

try {
Class.forName(DRIVER);
conn = DriverManager.getConnection(URL);
pst = conn.prepareStatement("select * from userinfo");
rs = pst.executeQuery();
while (rs.next()) {
System.out.println(rs.getString(1) );
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
conn.close();
pst.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
