Subject: Re: Scheduling using CRON driven on Windows OS
My GenerateFlowFile processor is enabled and started
with
Scheduling Strategy: Cron Driven
Run Schedule : 02 10 * * * ?
This I expects to generate a flow file daily at 10:02 am, but from my limited
test, it seems to take the second parameter as minutes, and generate a flowfile
hourly at 10 minutes after the hour, e.g. 10:10, 11:10, 12:10, 13:10...
Perhaps there is a bug in parsing system date format?
Attached is a simple template that I am using for testing.
Thanks,
Keith

Keith,
Was your processor running at all times? It has to be started and enabled.
I guess sharing the cron expression and maybe a quick screenshot will help next.

I tried setting Scheduling Strategy property to CRON Driven but does not seem
to work. Sometimes it would fire when not expected to and others not fire
when expected to.
This is on Windows OS and the processor I tried was GenerateFlowFile. Is CRON
Driven setting not designed to work on Windows OS?
Thanks,
Keith
