Wenchen Fan created SPARK-19496:
-----------------------------------
Summary: 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.
