Force Stop a Processor

[Devin Fisher <de...@perfectsearchcorp.com>]

Mostly a general questions.  The processor in question is a custom made one
that is obviously misbehaving. I'm looking into why the process doesn't
stop like like normal but I was wondering if there was a way to "force"
stop a process (kill the processor)? I know I can restart the nifi process
to stop the process but I was hoping for a way that was a little less
drastic.

I'm on version 0.6.0 and you don't want to see the code (it is a fairly
complex bridge to an ETL System (codebase) that we are moving off).  I
would have a attach half a dozen files to show you.

I can understand not wanting to use Thread.stop. Maybe consider making it a
command (right click in the UI) instead of an automatic action. But there
are plenty of reason not to use Thread.stop.

I would expect my code to respond appropriately to an Interrupt. Is there a
way to trigger this interrupt in a unit test?

Also, if you care to share the code for you processor we’ll be happy to look and help you find the problem.
As Joe pointed out we make every possible attempt to stop it, but if your custom code is blocking and does not react to interrupts then there is not much we can do stoping short of Thread.stop (which is something we are reluctantly contemplating)

Devin,

In the more recent versions of NiFi attempts to stop the processor
which are not successful after some period of time (I think 30
seconds) should result in the process being killed if possible and
NiFi should then move on again.

What version are you on?

Thanks
Joe
