---------------------------------
Summary: Framework should not allow removal of 'filename' or
'path' attributes
Key: NIFI-13200
URL: https://issues.apache.org/jira/browse/NIFI-13200
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Reporter: Mark Payne
Assignee: Mark Payne
Currently, the framework prevents processors from removing the 'uuid'
attribute. However, it does allow any other attribute to be removed. However,
there are many processors that assume that the 'filename' and 'path' attributes
exist, and they are intended always to exist - they are even assigned values
when the FlowFile is created. We should ensure that these attributes cannot be
removed.
Otherwise, configuring UpdateAttribute to remove these attributes can cause
follow-on processors to fail with unexpected NullPointerExceptions
