Date Tue, 25 Oct 2011 21:46:32 GMT

     [ https://issues.apache.org/jira/browse/HBASE-4508?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ted Yu updated HBASE-4508:
--------------------------

    Release Note: 
A new config parameter, hbase.connection.per.config, has been added.
If set to true, there is no connection sharing.
If set to false, connection sharing would be enabled so that fewer connections to zookeeper
are used.
