> Key: DRILL-5380
> URL: https://issues.apache.org/jira/browse/DRILL-5380
> Project: Apache Drill
> Issue Type: Bug
> Components: Documentation, Storage - Parquet
> Reporter: Rahul Challapalli
> Assignee: Bridget Bevens
>
> Drill used a wrong format for storing dates in parquet before 1.8.0 release
> and as a result it had compatibility issues with other parquet reader/writer
> tools. DRILL-4203 fixes that issue by providing an auto-correction capability
> in drill's parquet reader. However if someone really intends to use dates,
> which drill thinks are wrong, then we can use the approach to disable
> auto-correction by drill
> {code}
> select l_shipdate from table(cp.`tpch/lineitem.parquet` (type => 'parquet',
> autoCorrectCorruptDates => false));
> {code}
> This needs to be documented
