Subject [jira] [Created] (HBASE-10854) Multiple Row/VisibilityLabels visible while in the memstore
Date Thu, 27 Mar 2014 20:41:15 GMT
Matteo Bertozzi created HBASE-10854:
---------------------------------------

             Summary: Multiple Row/VisibilityLabels visible while in the memstore
                 Key: HBASE-10854
                 URL: https://issues.apache.org/jira/browse/HBASE-10854
             Project: HBase
          Issue Type: Bug
          Components: security
    Affects Versions: 0.98.1
            Reporter: Matteo Bertozzi


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

$ sudo -u hbase hbase shell
hbase> scan 'tb'
row column=f1:q, timestamp=1395948168102, value=v1all
1 row
{code}

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

$ sudo -u hbase hbase shell
hbase> scan 'tb'
0 row
{code}
