Description:
Following two queries run on same dataset should return same output. But they
are not.
This happens only with parquet data loaded on impala version 2.3.0 and queries
from Impala 2.11.0 after upgrade.

select count(timespan) from metrics where timespan between
cast(date_add('2018-04-06 14:37:00' , -7) as string) and '2018-04-06 14:37:00';
