Reason:

This issue can occur if the ambari-server hostname is setup differently in Ambari. For example :

Hostname –f shows hostname as ambari-server.abcxyz.net where as Ambari hosts information show the ip of this host instead of the fully qualified domain name. SmartSense still identifies the Ambari-Server based on its actual hostname rather than the ip being used as hostname in Ambari setup.

Solution:

Firstly, the actual hostname and the hostname configured in Ambari should be in sync.

This issue is fixed in SmartSense 1.3.1 onwards so upgrading to higher version can fix this issue. Otherwise, copy the jar /var/lib/ambari-agent/cache/stacks/HDP/2.1/services/SMARTSENSE/package/files/view/smartsense-ambari-view-[version].jar to /var/lib/ambari-server/resources/views/ and restart Ambari-Server and HST Server.
