> If we update the row multiple times with different visibility labels
> we are able to get the "old version" of the row until is flushed
> {code}
> $ sudo -u hbase hbase shell
> hbase> add_labels 'A'
> hbase> add_labels 'B'
> hbase> create 'tb', 'f1'
> hbase> put 'tb', 'row', 'f1:q', 'v1', {VISIBILITY=>'A'}
> hbase> put 'tb', 'row', 'f1:q', 'v1all'
> hbase> put 'tb', 'row', 'f1:q', 'v1aOrB', {VISIBILITY=>'A|B'}
> hbase> put 'tb', 'row', 'f1:q', 'v1aAndB', {VISIBILITY=>'A&B'}
> hbase> scan 'tb'
> row column=f1:q, timestamp=1395948168154, value=v1aAndB
> 1 row
