Joel Berger commented on NIFI-8492:
-----------------------------------
Please fix this, I wasted a whole day trying to figure out why this wouldn't
work, and to find that its a bug in nifi and one that's already been fixed
elsewhere was a real gut-punch. If it cannot be fixed perhaps at least update
the documentation to indicate that it is currently broken so that the next
person doesn't spend all day trying to understand the failure like I did.
> IPLookupService not working since 1.8.0?
> ----------------------------------------
>
> Key: NIFI-8492
> URL: https://issues.apache.org/jira/browse/NIFI-8492
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.11.4, 1.13.2
> Reporter: Benjamin Charron
> Priority: Major
> Labels: IPLookupService
>
> IPLookupService, like its cousin GeoEnrichIP, uses maxmind/DatabaseReader.java
> However, because they are in different NARs, they each have their own
> "DatabaseReader.java
> ". GeoEnrichIP's version had a bug fixed back in 1.9.0
> (https://issues.apache.org/jira/browse/NIFI-5814), but IPLookupService did
> not.
> As far as I can tell, IPLookupService has also been broken since 1.8.0. We
> get the following error with the IPLookupService in 1.11.4:
> {code}
> Caused by: java.lang.UnsupportedOperationException: null
> at java.util.Collections$UnmodifiableMap.put(Collections.java:1457)
> at
> com.fasterxml.jackson.databind.node.ObjectNode.set(ObjectNode.java:370)
> at
> org.apache.nifi.lookup.maxmind.DatabaseReader.get(DatabaseReader.java:158)
> at
> org.apache.nifi.lookup.maxmind.DatabaseReader.city(DatabaseReader.java:194)
> at
> org.apache.nifi.lookup.maxmind.IPLookupService.doLookup(IPLookupService.java:262)
> {code}
> Should the fixes in GeoEnrichIP's DatabaseReader also be copied to
> IPLookupService's DatabaseReader? Or is there a way for them to use the same
> one without copying the file?
