Connecting to Kerberos-enabled hive via JDBC directly from Java

[#1]

I have a Kerberos-enabled sandbox that I can connect to Hive via beeline after a kinit: !connect jdbc:hive2://localhost:10000/default;principal=hive/sandbox.hortonworks.com@EXAMPLE.COM

However, I need to connect directly from a Java program using the JDBC driver. A simple program fails to connect using the same URL that works for beeline above. I receive the following error:

Exception in thread "main" java.sql.SQLException: Could not open client transport with JDBC Uri: jdbc:hive2://localhost:10000/default;principal=hive/sandbox.hortonworks.com@EXAMPLE.COM: GSS initiate failed

Here is the simple program I am attempting to run:

import org.apache.hive.jdbc.HiveDriver;
import java.sql.SQLException;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;
import java.sql.DriverManager;
public class HiveJDBCTest{
        public static void main(String[] args) throws SQLException{
                try {
                        Class.forName("org.apache.hive.jdbc.HiveDriver");
                } catch (ClassNotFoundException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                        System.exit(1);
                }
                Connection cnct = DriverManager.getConnection("jdbc:hive2://localhost:10000/default;principal=hive/sandbox.hortonworks.com@EXAMPLE.COM");
                Statement stmt = cnct.createStatement();
                String sql = "show tables;";
                System.out.println("Running: " + sql);
                ResultSet res = stmt.executeQuery(sql);
                if (res.next()) {
                        System.out.println(res.getString(1));
                }
        }
}

Any thoughts?

Did you try adding /etc/hive/conf, it will be the location where your hive-site.xml is? AFAIK for a single user case you should not need to do anything with UGI object. For a multi-user case, you can do something like:

UserGroupInformation ugi = UserGroupInformation.loginUserFromKeytabAndReturnUGI(user, keytabfile);
Connection con = (Connection) ugi.doAs(new PrivilegedExceptionAction<Object>() {
      public Object run() {
        Connection tcon = null;
        try {
          tcon = DriverManager.getConnection(connectionURL, user, passwd);
        } catch (SQLException e) {}
        return tcon;
      }
});
