Connection to Hive fails

Anonymous — Wed, 30 Oct 2013 13:13:51 GMT

Hello,
I am new to talend and installed TOS for big data version 5.4.0. I am trying to connect to my Hive server using the tHiveConnection_1 component without success. Here are my settings:
Distibution: Cloudera Hive Version: Cloudera CDH4
Connection mode: Standalone Hive Server: Hive2
Host: "myURL" Port: "10000"
Database: "default"
Username: "" Password: ""
Set Jobtracker URL : "myURL:50030"
Set Namenode URI: "hdfs://myURL:8020

I am getting the following error:

Hi boniecarine,
im seeing a Connection refused error and also BAD URL Format.
Maybe there is something wrong with the URL jdbc:hive2://cdh-prod-001.ludia.me:10000/default ?
Best regards,
Marco
