I can tell Hive and MySQL do store per-row scale values. E.g.
https://github.com/apache/hive/blob/trunk/serde/src/java/org/apache/hadoop/hive/serde2/io/HiveDecimalWritable.java#L113.

This is true. This class is used as default LazySerde in Hive. However, other
Serde is free to choose its implementation.
I'm on board with storing scale per row. My only concern is that Hive
ParquetSerde is choosing not to store scale per row. Of course, this belongs to
a different discussion.
> Support for DECIMAL primitive type

> Key: AVRO-1402

> Project: Avro
> Issue Type: New Feature

> Currently, Avro does not seem to support a DECIMAL type or equivalent.
> http://avro.apache.org/docs/1.7.5/spec.html#schema_primitive
> Adding DECIMAL support would be particularly interesting when converting
> types from Avro to Hive, since DECIMAL is already a supported data type in
> Hive (0.11.0).
