   * <<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.
