Jurgis Pods commented on AVRO-1810: ----------------------------------- This issue means that the Avro 1.8 release ist practically unusable in conjunction with Kafka Connect, which I think affects quite a lot of users. Any plans on fixing this? Any workarounds other than * don't use enums in your schema or * downgrade to Avro 1.7.7? > GenericDatumWriter broken with Enum > ----------------------------------- > > Key: AVRO-1810 > URL: https://issues.apache.org/jira/browse/AVRO-1810 > Project: Avro > Issue Type: Bug > Components: java > Affects Versions: 1.8.0 > Reporter: Ryon Day > Priority: Blocker > > {panel:title=Description|titleBGColor=#3FA|bgColor=#DDD} > Using the GenericDatumWriter with either Generic OR SpecificRecord will break > if an Enum is present. > {panel} > {panel:title=Steps To Reproduce|titleBGColor=#8DB|bgColor=#DDD} > I have been tracking Avro decoding oddities for a while. > The tests for this issue can be found > [here|https://github.com/ryonday/avroDecodingHelp/blob/master/src/test/java/com/ryonday/test/Avro180EnumFail.java] > {panel} > {panel:title=Notes|titleBGColor=#3AF|bgColor=#DDD} > Due to the debacle that is the Avro "UTF8" object, we have been avoiding it > by using the following scheme: > * Write incoming records to a byte array using the GenericDatumWriter > * Read back the byte array to our compiled Java domain objects using a > SpecificDatumWriter > This worked great with Avro 1.7.7, and this is a binary-incompatable breaking > change with 1.8.0. > This would appear to be caused by an addition in the > {{GenericDatumWriter:163-164}}: > {code} > if (!data.isEnum(datum)) > throw new AvroTypeException("Not an enum: "+datum); > {code} > {panel} -- This message was sent by Atlassian JIRA (v6.4.14#64029)
