>
> The current implementation had the 'DATE' datatype bound to a Spark SQL
> 'TimestampType', which causes a casting error trying to convert from
> java.sql.Date to java.sql.Timestamp when using the DataFrame API with Phoenix
> DATE columns.
> This patch modifies the schema handling to treat DATE columns as the Spark
> 'DateType' instead. Note that Spark *drops* the hour, minute and second
> values from these when interfacing using DataFrames. This follows the
> java.sql.Date spec, but might not useful to folks who rely on the
> hour/minute/second fields working using the DataFrame API and DATE columns. A
> future improvement would be to force these to be TimestampTypes instead to
> preserve information, but it's less intuitive and probably shouldn't be the
> default behaviour.
