Cannot connect/query from Presto on AWS EMR with Java JDBC

If I ssh onto the master node of my presto emr cluster, I can run queries. However, I would like to be able to run queries from java source code on my local machine that connects to the emr cluster. I set up my presto emr cluster with default configurations.

I have tried port forwarding, but it still does not seem to work. When I create the connection, I print it out and it is "com.facebook.presto.jdbc.PrestoConnection@XXXXXXX" but I still have doubts if it is actually connected since I can't execute any queries and it always times out.

import java.net.URI;import java.net.URISyntaxException;import java.sql.*;public class PrestoJDBC {    // JDBC driver name and database URL    static final String JDBC_DRIVER = "com.facebook.presto.jdbc.PrestoDriver";    //static final String JDBC_DRIVER = "com.teradata.presto.jdbc42.Driver";    static final String DB_URL = "jdbc:presto://ec2-XX-XX-XXX-XX.us-east-2.compute.amazonaws.com:8889/hive/default";    //  Database credentials    static final String USER = "hadoop";    static final String PASS = "";    public static void main(String[] args) throws URISyntaxException {        Connection conn = null;        Statement stmt = null;        try{            //STEP 2: Register JDBC driver            Class.forName(JDBC_DRIVER);            //STEP 3: Open a connection            //conn = DriverManager.getConnection(DB_URL,USER,PASS);            conn = DriverManager.getConnection(DB_URL,USER,PASS);            //STEP 4: Execute a query            stmt = conn.createStatement();            System.out.println(conn);            String sql;            sql = "select * from onedaytest where readOnly=true;";            ResultSet rs = stmt.executeQuery(sql);            //STEP 5: Extract data from result set            while(rs.next()){                //Display values                System.out.println(rs.getString(3));            }            //STEP 6: Clean-up environment            rs.close();            stmt.close();            conn.close();        }catch(SQLException se){            se.printStackTrace();        }catch(Exception e){            e.printStackTrace();        }finally{            try{                if(stmt!=null)                    stmt.close();            }catch(SQLException se2){            }            try{                if(conn!=null)                    conn.close();            }catch(SQLException se){                se.printStackTrace();            }        }        System.out.println("Done");    }}

I get a java.sql.SQLEXception:Error executing query, and a java.net.SocketTimeoutException. I was wondering if there are any other configurations or things I need to setup to be able to query.
