I need help please has any one connected Radoop with Amazon EMR. I am trying to do that using rapidminer studio &radoop 7.3. I have followed the distribution notes for EMR and I have done all the steps but I got the following error:

Solved! Go to Solution.
the configuration looks like ok, but I assume, that you skipped the networking setup and a SOCKS proxy is not initialized. There is a "Setup networking" paragraph with a link to a SOCKS Proxy setup. Please check your SSH connection and SOCKS setup.
the error message indicates, that the client is not able to initiate a TCP connection to the Hive port.
Please check, that:
- you initiated the SOCKS connection to the master node
- Hive is running on that node, e-g- listens on the port 10000
- You did the port forwarding from localhost:10000 to the master node:10000 (-L 10000:localhost:10000 in the SSH settings)
