Ted Yu commented on HBASE-3488:
-------------------------------
R1:CF1:name and R2:CF1:name are the same column.
>> Do you mean to assume that all rows (R1..Rn) will have a CF, CF1 with ck
>> where (k = 1..20)
I meant you can associate columns ck (k=1..m) with CF1 and columns cl
(l=m+1..n) with CF2 for clarity. In reality columns of different column
families may have the same name.
Listing count of versions should be enough for individual columns.
> Allow RowCounter to retrieve multiple versions of rows

> 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
>
>
> 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}
