Vinayakumar B commented on HDFS-8976:
-------------------------------------
bq. It looks to me that there is no need to have yet another page. It can be
done by (1) adding a link to the federated cluster, and (2) rendering the
tmpl-dfshealth templates for each federated NN.
You mean, no need to Summarize ? Show all NN's info in multiple {{
tmpl-dfshealth}} templates?
> Create HTML5 cluster webconsole for federated cluster

> Since the old jsp variant of cluster web console is no longer present from
> 2.7 onwards, there is a need for HTML 5 web console for overview of overall
> cluster.
> 2.7.1 docs says to check webconsole as below {noformat}Similar to the
> Namenode status web page, when using federation a Cluster Web Console is
> available 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.{noformat}
