> This came from discussion with Stack w.r.t. HBASE-2195.
> There is currently a lot of duplicated code especially between Put and
> Delete, and also between all Operations.
> For example all of Put/Delete/Get/Scan have attributes with exactly the same
> code in all classes.
> Put and Delete also have the familyMap, Row, Rowlock, Timestamp, etc.
> One way to do this is to introduce "OperationWithAttributes" which extends
> Operation, and have Put/Delete/Get/Scan extend that rather than Operation.
> In addition Put and Delete could extends from Mutation (which itself would
> extend OperationWithAttributes).
> If a static inheritance hierarchy is not desired here, we can use delegation.
