							 I have one more cluster and there grafana is working fine.   I thing i observe there is:  https://<hostname>:8443 --- my ambari address  
And when i click on Grafana UI link its:  http://<hostname>:3000  so the difference here is grafana is going to http here not on https.  
can you tell me how can we resolve this?
