> Currently in DataFrame, we have API like:
> {code}
> def join(right: DataFrame, usingColumns: Seq[String]): DataFrame
> def dropDuplicates(colNames: Seq[String]): DataFrame
> def dropDuplicates(colNames: Array[String]): DataFrame
> {code}
> Those API not like the so friendly to Java programmers, change it to:
> {code}
> def join(right: DataFrame, usingColumns: String*): DataFrame
> def dropDuplicates(colNames: String*): DataFrame
> {code}
