Major Description
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
$ 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 $ sudo -u testuser hbase shell hbase> scan 'tb' row column=f1:q, timestamp=1395948168102, value=v1all 1 row
When we flush the memstore we get a single row (the last one inserted)
so the testuser get 0 rows now.
$ sudo -u hbase hbase shell hbase> flush 'tb' hbase> scan 'tb' row column=f1:q, timestamp=1395948168154, value=v1aAndB 1 row $ sudo -u testuser hbase shell hbase> scan 'tb' 0 row
