Subject Error handling in @OnScheduled
Date Thu, 23 Aug 2018 14:19:14 GMT
What is the best way to handle exceptions which might be thrown in my
@OnScheduled method? Right now, I'm logging and propagating the
exception which has the desired behaviour in NiFi (bulletin in GUI and
processor cannot be started) but when trying to add a unit test, the
(expected) exception is caught in and
failure asserted.

My actual @OnScheduled method builds a non-trivial object based on the
Processor's params - maybe I should be building that any time any of
the params change instead?

Many thanks,
