URL: https://github.com/apache/hbase/pull/614
 
 
   The leak is caused as said by @binlijin. The updateReaders() has already the memstoreScanners() list and so that is not getting closed. 
   We need to close the scanners if the close()  has already happened. The test case added here helps to identify the problem. Without the patch the test fails and with patch the test passes. 
   @chenxu14 - Pls take a look if this will solve the problem.
   @binlijin  - I just realised that the memstoreScanners() were passed by the Hstore#notifyChangedReadersObservers() and not got from the updateReaders().
