with ENUM original type values
[ https://issues.apache.org/jira/browse/DRILL-4156?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15789353#comment-15789353 ]
Marc Golinelli commented on DRILL-4156:
---------------------------------------
I experienced the same issue when querying parquet files written using an Avro schema, the first time I test Apache Drill.
Do you still plan to fix this issue ?
Thank you for your time.

> 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.
