Hello,

This is our first implementation of nifi in our company.

Our set up is as follows

Nifi Version - 0.4.0

Server 1 - NiFi Manager
Server 2 - MiFi Node1
Server 3 - MiFi Node2
Server 4 - MiFi Node3

/opt/nifi/run/instance_httpport
                    configuration_resources
                     logs
                     nifi-0.4.0                 
                     repository

Above set up works fine we can see NiFi UI and all the nodes connected.

Our Next Step is to test upgrade process to 0.4.1. After following upgrade 
procedure as mentioned here -
