Zoltán Borók-Nagy commented on IMPALA-7427:
-------------------------------------------

Impala already writes the version information in the "created_by" field. Adding
the same information under "writer.model.name" seems a bit redundant to me.
This property is probably more useful for Hive, where the creator is Parquet-MR
and they need to provide extra information about the Hive version.
Do you still think it's useful to fill "writer.model.name" for Impala as well?
