> The VisibilityLabelFilter will see and count the "delete cell" if the scan.isRaw() returns
true, so the (put) cell will be skipped if it has lower version than "delete cell"
> The critical code is shown below:
> {code:title=VisibilityLabelFilter.java|borderStyle=solid}
>   public ReturnCode filterKeyValue(Cell cell) throws IOException {
>     if (curFamily.getBytes() == null
>         || !(CellUtil.matchingFamily(cell, curFamily.getBytes(), curFamily.getOffset(),
>             curFamily.getLength()))) {
>       curFamily.set(cell.getFamilyArray(), cell.getFamilyOffset(), cell.getFamilyLength());
>       // For this family, all the columns can have max of curFamilyMaxVersions versions.
No need to
>       // consider the older versions for visibility label check.
>       // Ideally this should have been done at a lower layer by HBase (?)
>       curFamilyMaxVersions = cfVsMaxVersions.get(curFamily);
>       // Family is changed. Just unset curQualifier.
>       curQualifier.unset();
>     }
>     if (curQualifier.getBytes() == null
>         || !(CellUtil.matchingQualifier(cell, curQualifier.getBytes(), curQualifier.getOffset(),
>             curQualifier.getLength()))) {
>       curQualifier.set(cell.getQualifierArray(), cell.getQualifierOffset(),
>           cell.getQualifierLength());
>       curQualMetVersions = 0;
>     }
>     curQualMetVersions++;
>     if (curQualMetVersions > curFamilyMaxVersions) {
>       return ReturnCode.SKIP;
>     }
>     return this.expEvaluator.evaluate(cell) ? ReturnCode.INCLUDE : ReturnCode.SKIP;
>   }
