> The actual issue stems to the different date parser used by various part of
> the engine.
> Fetch task uses udfdatediff via {code}
> org.apache.hadoop.hive.ql.udf.generic.GenericUDFToDate{code} while the
> vectorized llap execution uses {code}VectorUDFDateDiffScalarCol{code}.
> This fix is meant to be not very intrusive and will add more support to the
> GenericUDFToDate by enhancing the parser.
> For the longer term will be better to use one parser for all the operators.
> Thanks [~Rajkumar Singh] for the repro example
> {code}
> create external table testdatediff(datetimecol string) stored as orc;
> insert into testdatediff values ('2019-09-09T10:45:49+02:00'),('2019-07-24');
> select datetimecol from testdatediff where datediff(cast(current_timestamp as
> string), datetimecol)<183;
> set hive.ferch.task.conversion=none;
> select datetimecol from testdatediff where datediff(cast(current_timestamp as
> string), datetimecol)<183;
