JDBC from Oracle Data Integrator to Kerberized HDP : Connection refused

Expert Contributor

ODI studio 12.2.1.2.6

Kerberized HDP 2.6.3.0

Windows 7

hive-jdbc-2.1.0.2.6.3.0-235-standalone.jar(that is available under /usr/hdp/2.6.3.0-235/hive2/jdbc)

I simply get a 'Connection refused', also, I didn't find any answers to the following Exception:

Caused by: java.lang.RuntimeException: java.lang.RuntimeException: class org.apache.hadoop.security.JniBasedUnixGroupsMappingWithFallback not org.apache.hadoop.security.GroupMappingServiceProvider

The complete error:

I have added the necessary config. in the odi.conf file

I have added the necessary configs. in the odi.conf

AddVMOption -Djava.security.krb5.conf=C:\Oracle\Middleware\Oracle_Home\oracle_common\modules\datadirect\kerb5.conf
AddVMOption -Djavax.security.auth.useSubjectCredsOnly=false

I am sure that the JDBC driver + my kerberos ticket cache etc. are in place, the below, stand-alone Java class is working fine:

package com.my;

import java.sql.*;

/** * Hello world! * */public class App
{
public static void main( String[] args ) throws ClassNotFoundException, SQLException {
System.out.println( "Hello World!" );

System.setProperty("javax.security.auth.useSubjectCredsOnly","false");
System.setProperty("java.security.krb5.conf","C:\Oracle\Middleware\Oracle_Home\oracle_common\modules\datadirect\kerb5.conf");
//System.setProperty("sun.security.krb5.debug","true");Class.forName("org.apache.hive.jdbc.HiveDriver");
System.out.println("getting connection");
Connection con = DriverManager.getConnection("jdbc:hive2://l4284t.sss.se.scania.com:10501/;transportMode=http;principal=hive/_HOST@GLOBAL.SCD.SCANIA.COM;httpPath=cliservice");
System.out.println("Connected");

Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("show tables");
while (rs.next()){
System.out.println("table name : "+rs.getString(1));
}
stmt.close();
con.close();
}
}

Did you have a look at this document

Yeah, I have tried that approach as well. The ODI doc. mentions about using it's weblogic hive jdbc driver but one can use other drivers as well. The question that I have mentioned here is around the standard(Apache)jdbc driver.
