Re: TestRunner fileSize Attribute

2019-02-26 Thread Shawn Weeks 
I found the code for it that inserts those like they were attributed in 
ValueLookup. To further confuse it some processors appear to set an attribute 
of that name.

Thanks for explaining that I was a bit confused.

Shawn,

I think it is presented that way in the given link because it is accessed via 
the Expression Language by using ${fileSize} - the same as if it were an 
attribute.
So from the point of view of the user/flow designer, they can be assumed to be 
the same. However, from the POV of a developer working on a processor,
it is obtained via getSize() because it is not truly an attribute.

Thanks

Hi Shawn,

filename and uuid are attributes of the FlowFile. There's no fileSize attribute

Does that help?

Re: TestRunner fileSize Attribute

2019-02-26 Thread Matt Burgess 
Shawn,

Searching the codebase, I couldn't really find (m)any places where
"fileSize" is set as a flow file attribute. It is available via the UI
(which I presume calls flowFile.getSize()) as well as in provenance
events (again populated by flowFile.getSize() not an attribute per
se). That documentation appears incorrect, I wonder if it was meant to
refer to available "attributes" (really metadata) on provenance events
for a flow file.

Regards,
Matt

fileSize is listed as a default attribute for a flow file along with uuid and 
filename. It always seems to be populated in a real workflow. It’s also listed 
here 
https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.1.1/bk_getting-started-with-apache-nifi/content/common-attributes.html
 and while they aren’t they only supporting organization I know they do quiet a
