Subject DUCC and CAS Consumers
Date Wed, 11 Apr 2018 09:16:00 GMT
Hi all,

I am doing my first steps with UIMA DUCC. I stumbled across the issue that my CAS consumer
has allowMultipleDeployments=false since it is supposed to write multiple CAS document texts
into one large ZIP file.
DUCC complains about the discrepancy of the processing AAE being allowed for multiple deployment
but one of its containers (my consumer) is not.
I did specify the consumer with the "process_descriptor_CC” job file key and was assuming
that DUCC would take care of it. After all, it is a key of its own. But it seems the consumer
is just wrapped into a new AAE together with my annotator AAE. This new top AAE created by
DUCC causes the error: My own AAE is allowed for multiple deployment and so are its delegates.
But the consumer not, of course.

How to handle this case? The documentation of DUCC is rather vague at this point. There is
the section about CAS consumer changes but it doesn’t mention multiple deployment explicitly.

What is the “process_descriptor_CC” for when it get wrapped up into an AAE with the user-delivered
AAE anyway?

Thanks and best regards,

Erik
