Hi Isha, When you say it was “copied” what precisely do you mean? 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
