> PARQUET-352 added support for the "writer.model.name" property in the Parquet metadata to identify the object model (application) that wrote the file.
> The easiest way to write this property is by overriding getName() of org.apache.parquet.hadoop.api.WriteSupport. In Hive, this would mean adding getName() to the org.apache.hadoop.hive.ql.io.parquet.write.DataWritableWriteSupport class.
