Subbu M Iyer commented on HBASE-3488:
-------------------------------------

Ted/Stack:

thanks a lot for your valuable review comments.

I don't think I understand when you say you want to port it to 0.90.3? What does that require
exactly? will be more than happy to address that.

> 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}
