Jacques Nadeau updated DRILL-4070:

Metadata Caching : min/max values are null for varchar columns in auto
partitioned data)

> Project: Apache Drill
> Issue Type: Bug
> Components: Metadata
> Affects Versions: 1.3.0
> Reporter: Rahul Challapalli

> Attachments: cache.txt, fewtypes_varcharpartition.tar.tgz

> git.commit.id.abbrev=e78e286
> The metadata cache file created contains incorrect values for min/max fields
> for varchar colums. The data is also partitioned on the varchar column
> {code}
> refresh table metadata fewtypes_varcharpartition;
> {code}
> As a result partition pruning is not happening. This was working after
> DRILL-3937 has been fixed (d331330efd27dbb8922024c4a18c11e76a00016b)
> I attached the data set and the cache file
