Pierre Villard commented on NIFI-5340:
--------------------------------------
Working with a cluster does not require additional settings to work with the
NiFi Registry. I assume there is a component to be stopped while changing from
version A to B and this component cannot be successfully stopped causing the
error you're seeing. Can you share more details about what components are used
in the workflow you want to update? In particular does it reference controller
services? any particular processors that could require a long time to be
stopped gracefully?

>
> Hello, we recently updated our NiFi version to 1.6.0 and got ability to
> synchronize flows in our environments via versioning i.e NiFi Registry. It
> works pretty well when we try to fetch the latest flow version from the
> Registry into a standalone NiFi server (without clustering mode).
> However, when we try to update the flow in our environments where we run NiFi
> in cluster mode composed of 3 nodes we got a failure:
> ```Failed to update flow to new version due to
> org.apache.nifi.web.util.LifecycleManagementException: Failed while waiting
> for components to transition to state of STOPPED```
> I attached a screenshot with this alert. Could you shed some light on this ?
> Does cluster mode require any additional settings in order to work with NiFi
> registry ? Let me know if you need more info
