----------------------------------------
Summary: Document the usage of drill's parquet "date auto
correction" flag
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
