anchor.diff:  A NiFi cluster is comprised of one or more 'NiFi Nodes' (Node) controlled
   by a single NiFi Cluster Manager (NCM).  The design of clustering is a simple
   master/slave model where the NCM is the master and the Nodes are the slaves.

  +The NCM's reason for existence is to keep track of which Nodes are in the cluster,
   their status, and to replicate requests to modify or observe the 
   flow.  Fundamentally then the NCM keeps the state of the cluster consistent.

   instructed to continue operating as they were to ensure the data flow remains live.
   The absence of the NCM simply means new nodes cannot come on-line and flow changes
   cannot occur until the NCM is restored.

  Guaranteed Delivery::
  A core philosophy of NiFi has been that even at very high scale guaranteed delivery
  is a must.  This is achieved through effective use of a purpose-built persistent 
  write-ahead log and content repository.  Together they are designed in such a way
  as to allow for very high transaction rates, effective load-spreading, copy-on-write,

      User to system;;
          NiFi enables 2-Way SSL authentication and provides pluggable authorization so that it can properly control
          a user's access and at particular levels (read-only, dataflow manager, admin).  If a user enters a 
          sensitive property like a password into the flow, it is immediately encrypted server side and never again exposed
          on the client side even in its encrypted form.
