RE: DistributedMapCacheServer not included when making copy of ProcessGroup
Sure, I will create a ticket Thanks for looking into it! Isha Van: Mark Payne Verzonden: woensdag 19 januari 2022 15:56 Aan: users Onderwerp: Re: DistributedMapCacheServer not included when making copy of ProcessGroup OK thanks. So that is not intended to happen. It’s a bug. Good news is that I was able to easily replicate by creating a new process group, just adding the distributed map cache server, and then copy & paste. Not sure why it would do that, but we can certainly look into it. You mind filing a Jira for it?

Did you copy & paste the Process Group? Did you create a template and then instantiate it? Did you download the flow definition and then upload it again? There are a few different mechanism that you can use for duplicating process groups.

It turns out that during development the entire process group was copied to test some changes and then the copy was used from there on. A bit of testing shows that in NiFi 1.15.2 the DistributedMapCacheServer is silently excluded from the copy operation. I found no warnings or errors in the log concerning the operation. I can imagine this is done on purpose since a copy using the same port could never work, but I would expect either a warning, or for the validation/enabling of the copy to fail. Is this by design and are the DistributedMapCacheServer services supposed to be created at the root level, or can I create a bug/improvement ticket for this? Kind regards, Isha Lamboo

Hi Mark, It happens when using copy & paste to duplicate the Process Group on the canvas. We’ve since committed the fixed process group to the registry from the dev server and the DistributedMapCacheServer is created successfully when changing version on the production server, so the component must be present in the flowdefinition.
