-----------------------------------
Summary: MergeContent unexpected behaviour
Key: NIFI-11369
URL: https://issues.apache.org/jira/browse/NIFI-11369
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.20.0
Reporter: Tamas Neumer
Hi,
I would like to merge FlowFiles and came across the following documentation:
[https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-standard-nar/1.20.0/org.apache.nifi.processors.standard.MergeContent/additionalDetails.html|https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-standard-nar/[%E2%80%A6].nifi.processors.standard.MergeContent/additionalDetails.html]
Quoting from it: _"It is not necessary that all FlowFiles have this value, but
at least one FlowFile in the bin must have this value or the bin will never be
complete..."_
I have built a flow that assigns the following attributes to the FlowFiles:
* fragment.identifier
* fragment.index
* segment.original.filename
As stated in the documentation mentioned above, the attribute fragment.count is
just assigned to the last FlowFiles with the correct number.
The error I experience is that all the flow files without fragment.count
provoke an error stating:
...... Cannot Defragment ...because it does not have an integer value for the
fragment.count attribute; routing to failure
Could you help us out please?
Thank you!
Kind regards,
Florian and Tamas
