All processors stopped on startup
I upgraded a nifi 1.1.1 cluster to 1.2.0, and I'm now finding that all
processors are stopped on startup. However, the flow.xml.gz on disk
appears to have the correct scheduledState values. I'm afraid to touch the
flow in the UI, lest it save all 500 of my processors as stopped.
Is there anything new in 1.2.0 that would cause this?

So, this may be related to how the cluster propagates the flow.xml.gz. I
noticed that when I cleared every bit of state that I know about from NiFi
and then put my original flow.xml.gz in the conf directory of "node 1" and
deleted it from nodes 2-4, it came up with the processors correctly
started. However, the flow.xml.gz file on "node 1" has almost 500
instances of the word "RUNNING" in it, while the flow.xml.gz file on nodes
2-4 have only 10 instances of the word "RUNNING". Even when I make updates
on nodes 2-4 via UI and it updates the flow.xml.gz file on disk, it still
says "STOPPED" for almost everything on nodes 2-4 but "RUNNING" for almost
everything on node 1.

I too have encountered all processors being stopped after restarting 1.2.0.
(I am running a single node.) This happened several times, but on at least
one occasion they remained running. I am pretty sure that in my case when
the UI showed them stopped they really were stopped, and not running
surreptitiously.

One more key observation.. it actually appears that the processors are
running, even though their icons show that they are stopped. For example,
the tasks/time keeps going up even though a GetSQS processor looks
stopped. However, the fact that they appear stopped also seems to be
confusing the UI, which prevents me from starting any processors that
happen to have a thread running.
