When I do Select ST_Point(25,45) in PostgresQL I get the following : " 010100000000000000000039400000000000804640 " , whoever when I do the same thing in Hive I get this : (see the picture). If that was the only problem I wouldn't mind but when I do Select ST_Azimuth(ST_Point(25,45) , ST_Point(75,100)) I get this error : FAILED: SemanticException [Error 10014]: Line 1:7 Wrong arguments '100': No matching method for class ST_Azimuth with (binary, binary).
