> In testing out the SummingCombiner, I set the Combiner#COLUMNS_OPTION which led me to believe that the SummingCombiner would limit columns to the set that is provided as an option through the IteratorSetting.
> In practice, this was not the case as Combiner#findTop isn't used, and thus that column list is not adhered to. I can get the expected functionality out of SummingCombiner by calling {{ScannerBase#fetchColumn}} or {{ScannerBase#fetchColumnFamily}}.
