Wenchen Fan commented on SPARK-19496:
-------------------------------------
The weird part is, Spark may have different behaviors depend on if the format
is given. I think we should make it consistent, always return null or return
calculated dates.
> to_date with format has weird behavior

> Key: SPARK-19496
> URL: https://issues.apache.org/jira/browse/SPARK-19496
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.1.0
> Reporter: Wenchen Fan
>
> Today, if we run
> {code}
> SELECT to_date('2015-07-22', 'yyyy-dd-MM')
> {code}
> will result to `2016-10-07`, while running
> {code}
> SELECT to_date('2014-31-12') # default format
> {code}
> will return null.
> this behavior is weird and we should check other systems like hive to see if
> this is expected.
