> ------------------------------------------------------

> *Sequence time field steps for date start/end looks strange in spark as
> follows:*
> scala> sql("select explode(sequence(cast('2011-03-01' as date),
> cast('2011-05-01' as date), interval 1 second))").head(3)
> res26: Array[org.apache.spark.sql.Row] = Array([2011-03-01], [2011-03-01],
> [2011-03-01])
> scala> sql("select explode(sequence(cast('2011-03-01' as date),
> cast('2011-05-01' as date), interval 1 minute))").head(3)
> res27: Array[org.apache.spark.sql.Row] = Array([2011-03-01], [2011-03-01],
> [2011-03-01])
> scala> sql("select explode(sequence(cast('2011-03-01' as date),
> cast('2011-05-01' as date), interval 1 hour))").head(3)
> res28: Array[org.apache.spark.sql.Row] = Array([2011-03-01], [2011-03-01],
> [2011-03-01])
> *While this behavior in Prosto make sense：*
> presto> select sequence(date('2011-03-01'),date('2011-03-02'),interval '1'
> hour);
> Query 20200624_122744_00002_pehix failed: sequence step must be a day
> interval if start and end values are dates
> presto> select sequence(date('2011-03-01'),date('2011-03-02'),interval '1'
> day);
> _col0
> [2011-03-01, 2011-03-02]
