> When HA is enabled, Ambari is showing all the Nagios alerts for both NameNodes.
> There are several problems.
> 1. Alerts for HDFS as a service are duplicated (aggregate alerts):
> Blocks health
> 2. Alerts for individual NameNodes cannot be distinguished from each other. For example,
there are two entries for "NameNode host CPU utilization" and "NameNode Web UI" but you can't
tell which one belongs to which.
