Hi All,


I want to know the internal's of carbondata , recently i read the  CarbonSqlParser class , I just came some questions ?


some parser using hiveql to parse statement , some use scala parser combination for example :
line 289 createTable parser, the implement using  val node = HiveQlWrapper.getAst(statement) to parse create table statement,
line 992 loadDataNew use scala parser combination parser statement
So what's the different of these two implementions ?  can we replace hiveql parser to scala parser ?
 
Thx
