@MattWho  Wow! I think this pattern would work best for my usecase. I hadn't even considered the first challenge you brought up of production flows having their Parameter Context unassigned if I were to update their version. That would've been painful to find out after deploying many instances.   Back in NiFi 1 I used to handle situations such as this with variables, since they could just be directly attached to Process Groups and so I never had to worry about creating separate objects (parameters) and ensuring they get attached, or that every new instance of a versioned flow had to have its own unique context created. It's been a couple years but I believe I even questioned Pierre about this in one of his appearances in the Israeli NiFi meet-ups.   In regards to product work, I've ran into this case of trying to use NiFi as the underlying tool for different SaaS platforms multiple times already. There could definitely be some QoL changes made to make such a use-case easier to implement with NiFi's flow registry, I guess the responsibility lies in people like me opening issues to bring them though 🙂   Thank you very much for the suggestions Matt!

Hello @MattWho thanks for the information.  I'm already running the process only on the Primary node.  I will monitor and take a thread dump if it occurs again.  ... View more

I regenterate the keystore with the common server name.  Nifi UI works but I thought I can find the username/password in the nifi-bootstrap.log  I found the username and password encrypted in login-identity-providers.xml PepeVo_3-1767988221393.png how can I decrypt them, or should I generate a new username/password and how? thank you.

@Pashazadeh  Apache NiFI 2.0.x was a technical milestone/preview releases that underwent many changes before the first GA release with NiFi 2.1.x.  I would not expect a change in behavior going forward, unless some bug is introduced or the community agrees on a change in functionality/behavior.   While I don't have a specific answer to what bug resulted in the difference in behavior you encountered, here are some changes that affected the JsonRecordSetWriter. NIFI-14331 NIFI-13963 / NIFI-13843 NIFI-12670 If you still have your NiFi 2.0.0 running, you could run your flow using a convertRecord with same record readers and writers and then compare the output content with what you see with 2.7.1 output.  Maybe that can help figure out what is happening and if either of those bugs affecting earlier NiFi 2.x versions is related.

@MuruganFinastra  Since you are getting a 403 response, the first thing you should do is see what user identity this 403 is being returned for.  For this you'll want to be tailing the nifi-user.log while you attempt to make this rest-api call. You will see the denied related log lines in the nifi-user.log.  That logging will provide the user identity string and which NiFi authorization policy required for which that user identity did not have the required permissions.   Using this output, we can determine the next steps required here.  Is the expected user identity being logged? What is the logged authorization policy resulting in the 403 response? Also which user authentication and authorization configuration options are you using in your setup?
