> The object org.apache.spark.sql.catalyst.encoders.RowEncoder is critical when constructing a Dataset that is not Dataset[Row] but still has Row in its type.  For example, consider the following:
> df.map(row => (row.getInt(0), row))(Encoders.tuple(Encoders.scalaInt, RowEncoder(df.schema))
> Alternatively, there could be a way to get the Encoder from Dataset directly; it's unclear why 'encoder' isn't a member of Dataset.
