Date Fri, 13 Jul 2012 23:52:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6394?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13414161#comment-13414161
] 

Zhihong Ted Yu commented on HBASE-6394:
---------------------------------------

{code}
+        replicatedScanner.close();
{code}
I was expecting 'replicatedScanner = null' following the above call.
