> Allow RowCounter to retrieve multiple versions of rows

>
> Key: HBASE-3488
> URL: https://issues.apache.org/jira/browse/HBASE-3488
> Project: HBase
> Issue Type: Bug
> Components: util
> Affects Versions: 0.90.0
> Reporter: Ted Yu
> Fix For: 0.92.0
>
> Attachments:
> 3488-Allow_RowCounter_to_retrieve_multiple_versions_of_rows-version2.patch,
> 3488-Allow_RowCounter_to_retrieve_multiple_versions_of_rows.patch
>
>
> 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}
