    Description

      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.
