Haha :)

Sorry to send you back to them, but the stack trace certainly makes it look
like a Katta problem - it's within the katta Client class that it's failing
to connect to another host, and port 20000 as shown isn't used by Hadoop.

Knowing little about Katta, I'd double check that you aren't running any
firewalls and that the two hosts are accessible from each other on port
20000 on those IPs shown in the logs.

Thanks
-Todd
