AVRO-1810: Fix GenericDatumWriter w/ enums (#462)
> GenericDatumWriter broken with Enum
> -----------------------------------
>
> Key: AVRO-1810
> URL: https://issues.apache.org/jira/browse/AVRO-1810
> Project: Apache Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.8.0
> Reporter: Ryon Day
> Priority: Blocker
> Fix For: 1.9.0, 1.8.4
>
>
> {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}
