> I faced this problem while working on HIVE-3086.
> Wanted to add a common interface to all the operator's confs.
> Currently, the operator signature is Operator<T extends Serializable>,
> which makes it difficult to add more methods to T.
> Created a common interface SerializableCloneable, and now 
> Operator<T extends SerializableCloneable>.
> If we want to add more methods to SerializableCloneable in the future,
> it wont require changing so many files, so submitting it as a separate patch.
