title: Nifi - Remote Process Group - PeerSelector
body: <p>I have build a simple Process Group. It generates a FlowFile with some random stuff in it and sends it to the Nifi Remote Process Group.
  This Remote Process Group is configured to send the FlowFile to localhost or in this case to my own Hostname (I have tried localhost as well).</p>
  
  <p>After this the FlowFile should Appear at the "From MiNiFi" input Port and is sended to the LogAttribute. Nothing Special.</p>

  <p><a href="https://pastebin.com/iigXdPCE" rel="nofollow noreferrer">authorizers.xml</a></p>
