> Since our parser defined based on antlr 4 can parse data type (see 
> CatalystSqlParser), we can remove 
> org.apache.spark.sql.catalyst.parser.DataTypeParser. Let's make sure the new 
> parser's functionality is a super set of DataTypeParser. Then, we can remove 
> DataTypeParser. For the object DataTypeParser, we can keep it and let it just 
> call the parserDataType method of CatalystSqlParser.
> *The original description is shown below*
> Right now, our DDLParser does not support {{decimal(precision)}} (the scale 
> will be set to 0). We should support it.
