[DataFrames] map function - 2.0

[Ninad Shringarpure]

Hi Team,

When going through Dataset class for Spark 2.0 it comes across that both
overloaded map functions with encoder and without are marked as
experimental.

Is there a reason and issues that developers whould be aware of when using
this for production applications. Also is there a "non-experimental" way of
using map function on Dataframe in Spark 2.0

Thanks,
Ninad
