> When importing parquet data written using a Thrift schema, Drill cannot cope with ENUMs. This was fixed elsewhere in DRILL-1775 but not in the DrillParquetGroupConverter class ([see mailing list thread|https://mail-archives.apache.org/mod_mbox/drill-user/201508.mbox/%3CCAK55V=+VjPAehMiJ8U=CRH182k4zvhGfxzfwzNaA9edWZWgXKg@mail.gmail.com%3E]).
> It appears that the ParquetToDrillTypeConverter class was updated to use a varbinary as it's default behaviour, but the DrillParquetGroupConverter class was not updated to do the same.
