---------------------------------
Summary: GrokReader does not allow named capture groups with
underscores in name
Key: NIFI-4094
URL: https://issues.apache.org/jira/browse/NIFI-4094
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.3.0
Reporter: Mika Borner
Priority: Minor
When writing a regular expression with a named capture group, underscore can't
be used.
Typically, underscore is a valid character for capture groups. As avro also
supports underscores, and GrokReader is used to write into avro schemas, this
should be fixed.
Example of non-working regex:
(?<my_namedcapturegroup>.*)
