+@CapabilityDescription("This processor aids in the testing and debugging
of the flowfile framework by allowing "
+ + "a developer or flow manager to force various responses to a
flowfile. In response to a receiving a flowfile "
+ + "it can route to the success or failure relationships, rollback,
rollback and yield, rollback with penalty, "
+ + "or throw an exception. In addition, if using a timer based
scheduling strategy, upon being triggered without "
+ + "a flowfile, it can be configured to throw an exception, when
triggered without a flowfile.\n"

I think the last "when triggered ..." is redundant

> Key: NIFI-1829
> URL: https://issues.apache.org/jira/browse/NIFI-1829
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Joe Skora
> Assignee: Joe Skora
> Priority: Minor
> Fix For: 1.0.0, 0.7.0
>
>
> The FlowDebugger processor allows a variety of Processor responses and
> failures to be simulated for testing, debugging, and troubleshooting the
> framework.
> Responses it can produce on receipt of a flowfile include Transfer to
> Success, Transfer to Failure, Rollback without Penalty, Rollback and Yield,
> Rollback with Penalty, and Throw an Exception. The properties indicate how
> many times that response should be thrown, for example if configured with
> Success=10 and Failure=40, it will transfer the first 10 flowfiles to
> Success, transfer the next 40 to Failure, and then repeat.
> Similarly, responses it can produce when triggered without a flowfile include
> Throw an Exception, Yield, and Return (do nothing).
