Hi All ,
I am familiar with Cloudera manager there is an option in it to fail over the Name node manually.
Could some body tell me how can do it in Ambari.
Thanks in Advance

If the automatic failover is enabled in the cluster, to trigger the failover from Ambari, do not restart the active NameNode but shutdown the zkfc daemon on the active NN machine (note that to restart the NN in a large cluster may take a long time). Restart that zkfc daemon after the failover happens.
