Thanks all for the support.
We resolved the issue by creating a new nar file itself. It seems the old
version code was using some outdated dependencies which was not getting
fixed when upgrading the processor.

I find strace (or procmon for Windows) very handy to debug such resource
loading issues.

I was making sure you didn't have any code that was dependent on the
internal structure of how the NARs are unpacked.
I can't explain why it can't find the application-context.xml since I
don't have access to your code, but I don't see why that would be
related to moving to NAR_INF from META_INF,
Its inside one of the jars within the NAR_INF folder. Does it need to be
somehwere else?
Also I think we extended the AbstractNiFiProcessor from the custom kylo
processor while migrating it as kylo processor was not working as is in our
environment.. Will check that and have it packaged in the proc
Where is application-context.xml in your NAR?
And how are you trying to load it in
com.thinkbiganalytics.nifi.processor.AbstractNiFiProcessor
?
I would expect it to be packaged into the jar that contains your
processors, most likely in src/main/resources of the processors module
which then ends
Ahh, seems like a Springboot error.
Is it to do with upgraded Jetty server ?

You have to add another instance of the processor which should
generate the same stracktrace you sent earlier, except this time there
should be a second part to it with "Caused by " and then more of
the stacktrace that wasn't there before.

Can you edit logback.xml and add the following, the get the stacktrace again?
This should include a root cause exception which we are missing right now.
I think it takes about 20-30 seconds for logback to pick up the edits
to logback.xml.

The processor is used to scan metadata of an incoming flow file.
The error we get in logs is as below.

Without access to the code for your NAR I can only really guess, but it
sounds like an exception is happening when trying to call the constructor
of your processor and then it bounces into creating a ghost processor.
What is in the logs at the time you get the ghost processor?

Does that mean I need to recreate the processor? Or there is some
workaround?
The processor gets unpacked and its bundled dependencies go in NAR_INF.
However when I drag the processor on the canvas, it comes with a yellow
triangle (and gives the error message I stated above) and properties are

I don’t remember all the reasoning behind the change, but it had to do with
an issue when we upgraded Jetty...

Yes it does show as an option.
One thing I noticed is that the when the nar is unpacked, the bundled
dependencies are inside META_INF in the work folder in NiFi 1.6.0, however
in NiFI 1.9.0 they go inside NAR_INF.
Why does this happen?
It seems the custom processor that we have uses Springboot, and
Does that custom processor type show as an option if you try to add a new
processor to the canvas?

Hi Mike and Bryan,
One of my custom processors appears as inactive in NiFi with a yellow
triangle error.
When I hover over it I see a message saying 'Missing Processor' validated
against 'Any Property' is invalid. This is not a valid processor.
In the log it seems to invoke GhostProcessor.java whi
Thanks Mike and Bryan.
Yes it seems my template was still referring the old version.
I will have it updated now and will reimport.
Also the version of NiFi we are using is the one that comes with CDF. I am
not sure if CDF supports 1.9.2 yet or not. I will reach out to Cloudera and
see if we can get
What is in the template for the bundle coordinates of your processor?
and does that match the coordinates of the NAR that is deployed?
Example:

If you made a new version of your NAR, say 2.0.
If it's happening immediately upon trying to import the template, I believe
that's the error message saying that the 1.9 instance cannot find the NAR
file which provided the processor. Also, if you're referring to 1.9.0 and
not 1.9.2 you're going to want to upgrade to the latter because there are a
Thanks Bryan.
My custom processors are part of a template. However when I try to import
my template in NiFi 1.9, I get an error message saying
PutFeedMetadata is not known to this NiFi instance. I did update all the
dependencies to NiFi 1.9 and even the plugins. We are using a Cloudera

Hello,
Most likely your processor built against 1.6 would run fine in 1.9,
but to make sure you just need to update any nifi dependencies in your
poms to 1.9.2.
If you created your project from the archetype and didn't change
anything, then this should just be changing the parent in the root pom
Hi,
If we have a custom processor that was created with NiFi 1.6, what are the
steps we need to follow to make it work in 1.9?
Is there some sort of steps that explains the jar and pom updates we need
to do for making it work in 1.9?
