I do have installed Virtual BOX HDF 3.0 on Mac OS X.
when I install minifi in the VM the communication with the site2site remote.port (10000) works fine.
From my MacOS environment it complains:
2017-07-24 11:00:39,200 WARN [NiFi Site-to-Site Connection Pool Maintenance] o.apache.nifi.remote.client.PeerSelector Could not communicate with sandbox-hdf.hortonworks.com:10000 to determine which nodes exist in the remote NiFi cluster, due to java.io.EOFException

I did setup port forwarding in my VirtualBox.
I have tried different values for port and host, but all fail.
Somewhere I read that I have to set the port forwarding from VB to the Docker, but I was not able to find out how,
Which step am I missing?
You may find my answer to a previous question useful:
This details how to open a port on the docker guest so that you can access it from the VM host.
