Hello there, While looking at the features of Dataset, it seem to provide an alternative way towards udf and udaf. Any documentation or sample code snippet to write this would be helpful in rewriting existing UDFs into Dataset mapping step. Also, while extracting a value into Dataset using as[U] method, how could I specify a custom encoder/translation to case class (where I don't have the same column-name mapping or same data-type mapping)?
Please advice, Muthu
