> I think it's because of using changing from KeyValue to a different sub-class of {{Cell}}l
which doesn't implement {{SettableSequenceId}}
> {noformat}
> -    this.startKey = KeyValueUtil.createFirstDeleteFamilyOnRow(scan.getStartRow(),
> +    this.startKey = CellUtil.createFirstDeleteFamilyCellOnRow(scan.getStartRow(),
> {noformat}
> To replicate it, download the attached hfiles somewhere, copy the TestWithSingleHRegion
class to regionserver tests, change the ROOT_DIR appropriately and run it.
