ChiaPing Tsai resolved HBASE-16113.
-----------------------------------
      Resolution: Not A Problem
    Release Note: I misunderstood what the "max versions" meant

>                 Key: HBASE-16113
>                 URL: https://issues.apache.org/jira/browse/HBASE-16113
>             Project: HBase
>          Issue Type: Bug
>            Reporter: ChiaPing Tsai
>            Priority: Trivial
>
> Step 1: put a cell
> Step 2: delete the cell
> Step 3: Scan#setRaw(true).setMaxVersions(0)
> Step 4: Result result = table.getScanner(scan).next()
> Step 5: The result will contain a Cell of DELETE type
> Is it a correct result ? The critical code is shown below:
> {code:title=ScanWildcardColumnTracker.java|borderStyle=solid}
> // May be we should check the verion first
>   private MatchCode checkVersion(byte type, long timestamp) {
>     if (!CellUtil.isDelete(type)) {
>       currentCount++;
>     }
>     if (currentCount > maxVersions) {
>       return ScanQueryMatcher.MatchCode.SEEK_NEXT_COL; // skip to next col
>     }
>     // keep the KV if required by minversions or it is not expired, yet
>     if (currentCount <= minVersions || !isExpired(timestamp)) {
>       setTSAndType(timestamp, type);
>       return ScanQueryMatcher.MatchCode.INCLUDE;
>     } else {
>       return MatchCode.SEEK_NEXT_COL;
>     }
>   }
> {code}
> Comments?
> Thanks
