Great, thank you! I realized that that PR does depend on PARQUET-2265
<https://github.com/apache/parquet-mr/pull/1049/files> for the writes to
work -- it's a very minor PR bringing the default Avro write behavior in
line with Avro read behavior. It unlocks a new functionality--being able to
specify an Avro DataModel via a Configuration key--and has no user-facing
effect on any existing behavior.

I created a cherry-pick PR containing both tickets here
<https://github.com/apache/parquet-mr/pull/1091> -- I tested my local
installation locally and on Hadoop, using Avro data containing logical
types, and confirmed that it's working as expected.

Thanks,
Claire
