Hi all, I’ve encountered an issue today where a DistributedMapCacheServer controller service was missing from a process group with a flow. 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
