Quick and dirty way of Accessing Apache Drill using Drill JDBC connectivity

its a quick and dirty way of accessing the Apache Drill using the Drill-JDBC Driver,make sure you have Drill JDBC DRIVER (drill-jdbc-all-1.1.0.jar ) in the classpath while running your java program.
Java Class:

package com.test;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;


public class DrillJDBCTest {

public static void main(String[] args) throws Exception{
Class.forName("org.apache.drill.jdbc.Driver");
Connection connection =DriverManager.getConnection("jdbc:drill:zk=node3.mapr.com:5181/drill/my_cluster_com-drillbits");
Statement st = connection.createStatement();
ResultSet rs = st.executeQuery("SELECT * from cp.`employee`");
while(rs.next()){
System.out.println(rs.getString(1));
}

}

}

After running generated class file you will see the following output
:::::::::::::::::::::::::::::::::::::::::::::::::::::::::
 printing  full name of the employee
