I am trying to connect Rapidminer to Hortonworks Sandbox 3.1 but for some reason it keeps failing. The Hortonworks Sandbox is running on Hyper-v. I receive the following error(Attached are the error log and XML file):

I tried connecting it by following the guideline for connecting RapidMiner to Hortonworks Sandbox, but it only applies to HDP 2.X(can't post the link) and is outdated.

Hi,

There seems to be some problem connecting to the MapReduce service, port 10020. If it is a virtual machine maybe you need to forward the ports.
