James Wing commented on NIFI-4215: ---------------------------------- Thanks, [~markap14] , for bringing these issues to our attention. I pushed a new commit to revert this change so it is not blocking, and we can take the time to make the right fix. [~WesleyLawrence], I think the builder approach is worth a look, although I also haven't figured out the chicken vs. egg schema creation with a builder. I like that part of your solution. > Avro schemas with records that have a field of themselves fail to parse, > causing stackoverflow exception > -------------------------------------------------------------------------------------------------------- > > Key: NIFI-4215 > URL: https://issues.apache.org/jira/browse/NIFI-4215 > Project: Apache NiFi > Issue Type: Bug > Affects Versions: 1.4.0 > Reporter: Wesley L Lawrence > Priority: Blocker > Fix For: 1.4.0 > > Attachments: nifi-4215.patch > > > Noticed this while attempting to use the AvroSchemaRegsitry with some complex > schema. Boiled down, Avro lets you define a schema such as; > {code} > { > "namespace": "org.apache.nifi.testing", > "name": "CompositRecord", > "type": "record", > "fields": [ > { > "name": "id", > "type": "int" > }, > { > "name": "value", > "type": "string" > }, > { > "name": "parent", > "type": [ > "null", > "CompositRecord" > ] > } > ] > } > {code} > The AvroSchemaRegistry (AvroTypeUtil specifically) will fail to parse, and > generate a stackoverflow exception. > I've whipped up a fix, tested it out in 1.4.0, and am just running through > the contrib build before I submit a patch. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
