-----------------------------------
Summary: Parquet group converter cannot cope with ENUM original
type values
Key: DRILL-4156
URL: https://issues.apache.org/jira/browse/DRILL-4156
Project: Apache Drill
Issue Type: Bug
Components: Storage - Parquet
Affects Versions: 1.3.0
Reporter: Chris Jansen
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=crh182k4zvhgfxzfwznaa9edwzwg...@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.
