---------------------------------------
Summary: RegexExtractorInterceptor on header values
Key: FLUME-2086
URL: https://issues.apache.org/jira/browse/FLUME-2086
Project: Flume
Issue Type: Improvement
Reporter: nicolas maillard
Priority: Minor
It would be nice to be able to apply the RegexExtractorInterceptor to
previously defined header values and not event text in some cases.
For example in the spoolingDirectory the name of the file might hold
information not present in the events. You could parse the file name to extract
a date or a type and use it as an extra header value.
A limited change to RegexExtractorInterceptor with a new parameter headerKy if
not empty in the intercept method we could match against
context.getString(headerkey) instead of event.getBody()
