> Unable to deserialize AVRO data when file schema and record schema are
> different and nullable
> ---------------------------------------------------------------------------------------------

> Key: HIVE-7049
> URL: https://issues.apache.org/jira/browse/HIVE-7049
> Project: Hive
> Issue Type: Bug
> Reporter: Mohammad Kamrul Islam

> Attachments: HIVE-7049.1.patch
>
>
> It mainly happens when
> 1 )file schema and record schema are not same
> 2 ) Record schema is nullable but file schema is not.
> The potential code location is at class AvroDeserialize
>
> {noformat}
> if(AvroSerdeUtils.isNullableType(recordSchema)) {
> return deserializeNullableUnion(datum, fileSchema, recordSchema,
> columnType);
> }
> {noformat}
> In the above code snippet, recordSchema is verified if it is nullable. But
> the file schema is not checked.
> I tested with these values:
> {noformat}
> recordSchema= ["null","string"]
> fielSchema= "string"
> {noformat}
> And i got the following exception <line numbers might not be the same due to
> mu debugged code version>.
> {noformat}
> org.apache.avro.AvroRuntimeException: Not a union: "string"
