[jira] [Created] (SPARK-29524) Unordered interval units

Maxim Gekk created SPARK-29524:
----------------------------------

             Summary: Unordered interval units
                 Key: SPARK-29524
                 URL: https://issues.apache.org/jira/browse/SPARK-29524
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 2.4.4
            Reporter: Maxim Gekk


Currently, Spark requires particular order of interval units in casting from strings - `YEAR` .. `MICROSECOND`. PostgreSQL allows any order:
{code}
maxim=# select interval '1 second 2 hours';
 interval
----------
 02:00:01
(1 row)
{code}
but Spark fails on while parsing:
{code}
spark-sql> select interval '1 second 2 hours';
NULL
{code}
