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.
