0: jdbc:drill:schema=dfs> select cast(name as varchar(30)), cast(create_time as timestamp)
create_time from student where cast(create_time as timestamp) = date '2014-05-31';

message: "Failure while parsing sql. < ValidationException:[ org.eigenbase.util.EigenbaseContextException:
From line 1, column 97 to line 1, column 146 ] < EigenbaseContextException:[ From line
1, column 97 to line 1, column 146 ] < SqlValidatorException:[ Cannot apply '=' to arguments
of type '<TIMESTAMP(0)> = <DATE>'. Supported form(s): '<COMPARABLE_TYPE>

]

The query run successfully in postgres and oracle.  Looks like these 2 rdbms implicitly convert
the date to timestamp.
