Ashish Kumar Singh reassigned HIVE-7657:
----------------------------------------
Assignee: Ashish Kumar Singh
> Nullable union of 3 or more types is not recognized nullable
> ------------------------------------------------------------
>
> Key: HIVE-7657
> URL: https://issues.apache.org/jira/browse/HIVE-7657
> Project: Hive
> Issue Type: Bug
> Components: Serializers/Deserializers
> Reporter: Arkadiusz Gasior
> Assignee: Ashish Kumar Singh
> Labels: avro
>
> Handling nullable union of 3 types or more is causing serialization issues,
> as ["null","long","string"] is not recognized nullable. Potential code
> causing issues might be AvroSerdeUtils.java:
> {code}
> public static boolean isNullableType(Schema schema) {
> return schema.getType().equals(Schema.Type.UNION) &&
> schema.getTypes().size() == 2 &&
> (schema.getTypes().get(0).getType().equals(Schema.Type.NULL) ||
> schema.getTypes().get(1).getType().equals(Schema.Type.NULL));
> // [null, null] not allowed, so this check is ok.
> }
> {code}
