------------------------------------
Summary: GrokReader - Add a failure option to unmatch behavior
options
Key: NIFI-4136
URL: https://issues.apache.org/jira/browse/NIFI-4136
Project: Apache NiFi
Issue Type: Improvement
Components: Extensions
Reporter: Pierre Villard
Assignee: Pierre Villard
At the moment, when using the GrokReader, if a line does not match the grok
expression (and is not part of a stack trace), the line can be either ignored
(the line will be completely skipped) or appended to the last field from the
previous line.
In the case where appending is not desired and that data should not be
ignored/deleted, we should add the option to route the full flow file to the
failure relationship. This way the flow file could be treated in a different
way (for example with SplitText and ExtractGrok to isolate the incorrect lines
and re-route the correct lines back to the Record processors).
