Matt,
Thank you for advice here and other pointers.  I will pass this on and see how 
I can get these suggestions addressed on this other system.

Regards,

Subject: Re: observing strange behavior nifi UI flow on a system from a recent 
nifi 0.6.x to nifi 1.3.x upgrade

Jeremy,

The behavior your describing happens when you do not have permissions to the 
root group. This is the behavior when the policies for the initial admin 
(configured either through the property or through a legacy 
authorized-users.xml file) are created but there is no existing flow.xml.gz in 
the conf directory. In this case, the admin can log in and grant themselves the 
necessary permissions to the root group. From the admin guide...

For a brand new secure flow, providing the "Initial Admin Identity" gives that 
user access to get into the UI and to manage users, groups and policies. But if 
that user wants to start modifying the flow, they need to grant themselves 
policies for the root process group. The system is unable to do this 
automatically because in a new flow the UUID of the root process group is not 
permanent until the flow.xml.gz is generated. If the NiFi instance is an 
upgrade from an existing flow.xml.gz or a 1.x instance going from unsecure to 
secure, then the "Initial Admin Identity" user is automatically given the 
privileges to modify the flow.

Hope this helps.

Matt

Greetings,
I’d like to describe some observations we are witnessing and to see if anyone 
has seen this before or has any thoughts on the matter.  Any helpful advice 
would be appreciated. I am remotely trying to help some folks on a system that 
has just been upgraded from nifi 0.6.x to 1.3.x.  They are simply running nifi 
via the “nifi.sh start” technique now and not as a service and have nuked their 
nifi repos to help avoid issues when upgrading.  On our development baseline 
we’ve done the upgrade smoothly to nifi 1.3.0 months ago and have never seen 
what is being described.  Thus, a nifi flow is being used that has already been 
updated months ago for nifi 1.3.0 and thus is already complaint.  I’ve also 
ensured our custom nars are in the nifi-lib dir, etc.  And, those custom nars 
were also upgraded months ago to use 1.3.0 compliant nifi processor related 
classes.

The observations occurring in NiFi UI:

1)       the nifi processors are coming up unlabeled and their outlines are 
skeleton-dotted-lines.

2)       all connections to each processor are each red dotted lines

3)       in the top left menu of the nifi where all the icons are for adding 
processors, input ports, etc., when a mouseover occurs, instead of seeing a 
hand, we see a the equivalent of a “do NOT symbol”.  (i.e. the symbol in the do 
not smoking sign)
I’ve had someone lightly look at the logs for anything special, especially the 
word “validation” in case there were any bizarre XML validation errors on the 
nifi flow file.  Again, any thoughts or advice would be appreciated.  Thanks.

Regards,
