[jira] [Created] (SPARK-19496) to_date with format has weird behavior

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.
