Subject Re: Failure when running a workflow created from a template from another NiFi version.
Date Wed, 08 Jun 2016 23:18:11 GMT
Hi James,


Here is the template.  Need to remove the .txt extension.

Note: I didn't bother to put in the correct flowfile xpath content for the processor to evaluate
to success result.


Thanks,
Keith

Keith,

Would you be able to share your sample template with us as an attachment, a GitHub Gist, or
something similar?

Thanks,

James

Hi Joe,

I created a simple workflow with EvaluateXPath and managed to repro the issue.
Here is the snapshot of the screen.  This is on Windows with 0.7.0 snapshot.    There is no
issue on 0.6.1 on Windows and 0.7.0 on Linux.

We can't roll back to 0.6.1 as we have a dependency on a feature in 0.7.0

Thanks,
Keith

Hi Joe,

Interesting... I didn't find anything in the nifi-app.log, however, I found these logged in
the nifi.user.log.

This is the message box I got when I tried to run my workflow:
Node azudevmgmt01.ds-iq.corp:10001 is unable to fulfill this request due to: EvaluateXPath[id=6c73cffa-0d34-3b25-94d4-14d115b8b62b]
is not in a valid state

Thanks,
Keith

Keith,

Can you collect more information on this from the nifi-app.log?  Not
in valid state should be associated with some exceptions and such that
ideally will be in the logs.

Thanks
Joe
