stack commented on HBASE-3488:
------------------------------

What Ted says, or, refactor RowCounter#createSubmittableJob breaking it up into smaller pieces
that can be reused by CellCounter's createSubmittableJob.. then you perhaps could subclass?

> Currently RowCounter only retrieves latest version for each row.
> Some applications would store multiple versions for the same row.
> RowCounter should accept a new parameter for the number of versions to return.
> Scan object would be configured with version parameter (for scan.maxVersions).
> Then the following API should be called:
> {code}
>   public KeyValue[] raw() {
> {code}
