Re: Hadoop 2.4.1 Verifying Automatic Failover Failed: Unable to trigger a roll of the active NN
Hi,

Thanks for your reply.
It was about StandBy Namenode not promoted to Active.
Can you please advise what the path of ZKFC logs?  

"Similar to Namenode status web page, a Cluster Web Console is added in federation to monitor the federated cluster at http://<any_nn_host:port>/dfsclusterhealth.jsp. Any Namenode in the cluster can be used to access this web page”
What is the default port for the cluster console? I tried 8088 but no luck.

Please advise.

Regards
Arthur
