Hi,
in Java, the CsvOutputFormat used to only emit Tuples, we know that these
are mutable, therefore they are reused. The ScalaCsvOutputFormat emits case
classes (Scala Tuples are in fact Case Classes). These are generally not
mutable, the fields cannot be changed. Therefore we have to create a new object
every time.
> Add CsvReader for reading into POJOs.
