* <<How can I initiate a manual failover when automatic failover is
configured?>>
- Currently, this facility is not yet implemented. Instead, you may simply stop
- the active NameNode daemon. This will trigger an automatic failover. This
- process will be improved in future versions.

+ Even if automatic failover is configured, you may initiate a manual failover
+ using the same <<<hdfs haadmin>>> command. It will perform a coordinated
+ failover.
