> The copy() method of the GenericRow class does actually not copy itself. The method just returns itself.
> Simple reproduction code of the issue:
>  import org.apache.spark.sql.Row;
>     val row = Row.fromSeq(Array(1,2,3,4,5))
>     val arr = row.toSeq.toArray
>     arr(0) = 6
>     row // first value changed to 6
>     val rowCopied = row.copy()
>     val arrCopied = rowCopied.toSeq.toArray
>     arrCopied(0) = 7
>     row // first value still changed (to 7)
