Subject [jira] [Commented] (HDFS-2231) Configuration changes for HA namenode
Date Wed, 10 Aug 2011 19:52:27 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2231?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13082621#comment-13082621
] 

Allen Wittenauer commented on HDFS-2231:
----------------------------------------

bq. That second scheme is not to use failover. In such a case, clients need to know about
where the active is running. Datanodes needs to know about where both active and standby is
running.

I think there is a major terminology disconnect.  "failover" implies an active and a standby.
