Connecting to Impala through JDBC

Talend data fabric 6.3 enterprise
Impala - Cloudera Hadoop 5.7 with Kerberos
When trying to connect with tImpalaConnection I get:
"Exception in component tImpalaConnection java.lang.IllegalArgumentException: Unrecognized Hadoop major version number: 0.20.205.0"
When trying to create a connection through meta data I get "Connection failure. You must change the Database Settings.
  java.sql.SQLException: java.util.concurrent.ExecutionException: java.lang.IllegalArgumentException: Can't get Kerberos realm"

When working through the shell with impala shell using kinit and a key tab it works.

I wanted to install a different JDBC driver, but couldnt find a suitable guide for that.

Any ideas?

Only one realm.
We have an all-in-one cloudera server+AD/DC server+windows workstation with Talend. Trying to connect from the workstation.
