I would suggest you take alook to DataFrames. Also, I do not think you
should implement comparators for user class as a whole, rather you should
get the attribute to sort/compar on and delete sorting to data type of
inherent attribute. Eg. sorting can be done by name and if so, it should be
string sorting. In that case, you can create another KeyValue RDD whr key
is the "chosen" attribute and value is user object and do a sortByKey.
