Ravindra Pesala commented on CARBONDATA-479:
--------------------------------------------

LOCAL is only used to keep the syntax synchronize with Hive. Right now there is no effect of LOCAL keyword on loading flow.

> In CarbonSqlParser.scala,

>     LOAD ~> DATA ~> opt(LOCAL) ~> INPATH ~> stringLit ~ opt(OVERWRITE) ~
>     (INTO ~> TABLE ~> (ident <~ ".").? ~ ident) ~
>     (OPTIONS ~> "(" ~> repsep(loadOptions, ",") <~ ")").? <~ opt(";") ^^ {
>       case filePath ~ isOverwrite ~ table ~ optionsList =>
>         val (databaseNameOp, tableName) = table match {
>           case databaseName ~ tableName => (databaseName, tableName.toLowerCase())
>         }
>         if (optionsList.isDefined) {
>           validateOptions(optionsList)
>         }
>         val optionsMap = optionsList.getOrElse(List.empty[(String, String)]).toMap
>         LoadTable(databaseNameOp, tableName, filePath, Seq(), optionsMap,
>           isOverwrite.isDefined)
>     }
> It seems that using Keyword LOCAL impacts noting. Loading data from hdfs or file just depends on the path.
