ASF GitHub Bot commented on PARQUET-1303:
-----------------------------------------
zebehringer commented on issue #482: PARQUET-1303 correct ClassCastException
for Avro @Stringable fields
URL: https://github.com/apache/parquet-mr/pull/482#issuecomment-389966912
TestReflectLogicalType.testWriteUUIDMissingLogicalType no longer throws
ClassCastException after this change. In one sense the test is no longer valid,
but in a strict sense it is since the UUID field in that test is not annotated
with @Stringable, but there doesn't seem to be any way to detect that in
AvroWriteSupport, so it now passing is a side effect of the change.

> Key: PARQUET-1303
> URL: https://issues.apache.org/jira/browse/PARQUET-1303
> Project: Parquet
> Issue Type: Bug
> Components: parquet-avro
> Affects Versions: 1.9.0, 1.10.0
> Reporter: Zack Behringer
> Priority: Minor
>
> Annotate a field in a pojo with org.apache.avro.reflect.Stringable and the
> schema will consider it to be a String field. AvroWriteSupport.fromAvroString
> assumes the field is either a Utf8 or CharSequence and does not attempt to
> use the field class' toString method if it is not.
