Yes. I believe its a necessary parameter if non default cluster I'd is used and given in the
connection url. You can check if it works with directory specified.

Is it necessary because I thought it is optional including the cluster ID

    Are you missing drill zk directory in connection url?
    By default, it's value is drill.

    jdbc:drill:zk=<zk name>[:<port>][,<zk name2>[:<port>]...
    <directory>/<cluster ID>;[schema=<storage plugin>]

    Hi Tushar,

    This example works just fine for me, you may want to use the template

    import org.apache.log4j.Logger;

    import java.sql.Connection;
    import java.sql.ResultSet;
    import java.sql.SQLException;
    import java.sql.Statement;
    import java.sql.Types;
    import java.sql.*;
    import java.io.*;
    import java.lang.*;
    import java.util.*;
    import java.util.Scanner;

    public class TestQuery {

    public static void main(String s[]) throws Exception {

        Connection conn = null;
        PreparedStatement prdstmnt = null;
        try {
                // Please replace test1302-145 with your hostname, name of host
    where Drillbit is up and running
                final String URL_STRING =
    "jdbc:drill:schema=dfs.tmp;drillbit=test1302-145";
                Class.forName("org.apache.drill.jdbc.Driver").newInstance();

                // Please replace username and password with your username and
    password
                conn = DriverManager.getConnection(URL_STRING,"mapr","mapr");
                prdstmnt = conn.prepareStatement("SELECT * FROM
    cp.`employee.json`");
                prdstmnt.executeQuery();
                prdstmnt.close();
        } catch (Exception e) {
           System.out.println(e.getMessage());
           e.printStackTrace();
        } finally {
            if(conn != null)
                try { conn.close(); } catch(SQLException sqlexcpn){
    sqlexcpn.printStackTrace(); }
            if(prdstmnt != null)
                try { prdstmnt.close(); } catch(SQLException sqlexcpn){
    sqlexcpn.printStackTrace(); }
            }
        }
    }
