Bryan Bende commented on NIFI-543:
----------------------------------
[~sivaprasanna] I don't have the cycles right now to review this, but regarding
the comment about 'Versioned Processor'...
Is there really anything we need to add there?
The versioned processor already has the scheduling strategy that the processor
was set to, this annotation on the NiFi side just forces it so that the
strategy would only ever be primary node. I'm not sure if there is a need for
versioned processor to also know that the processor itself was annotated with
this.
> Provide extensions a way to indicate that they can run only on primary node,

> There are Processors that are known to be problematic if run from multiple
> nodes simultaneously. These processors should be able to use a
> @PrimaryNodeOnly annotation (or something similar) to indicate that they can
> be scheduled to run only on primary node if run in a cluster.
