How to delete Grafana?

[#1]

To remove a already installed Grafana, following needs to be done:

1. Stop the AMS service from Ambari UI.

2. Execute following curl API commands to delete Grafana:

# curl -u admin:admin -i -H 'X-Requested-By: ambari' -X PUT -d '{"RequestInfo": {"context" :"Stop HDFS via REST"}, "Body": {"ServiceInfo": {"state": "INSTALLED"}}}' http://<strong><ambari-server-hostname></strong>:8080/api/v1/clusters/<strong><CLUSTERNAME></strong>...

# curl -u admin:admin -i -H 'X-Requested-By: ambari' -X PUT -d '{"RequestInfo": {"context" :"Stop HDFS via REST"}, "Body": {"ServiceInfo": {"state": "INSTALLED"}}}' http://<strong><ambari-server-hostname></strong>:8080/api/v1/clusters/<strong><CLUSTERNAME></strong>...

# curl -u admin:admin -H "X-Requested-By: ambari" -X DELETE  http://<strong><ambari-server-hostname></strong>:8080/api/v1/clusters/<strong><CLUSTERNAME></strong>...

# curl -u admin:admin -H "X-Requested-By: ambari" -X DELETE  http://<strong><ambari-server-hostname></strong>:8080/api/v1/clusters/<strong><CLUSTERNAME></strong>...

# curl -u admin:admin -X GET http://<strong><ambari-server-hostname></strong>:8080/api/v1/clusters/<strong><CLUSTERNAME></strong>...

3. Start the AMS service from Ambari UI.

Here:

Replace following :

<ambari-server-hostname> = FullyqualifiedDomain Nameof the node running Ambari Server

<CLUSTERNAME> = Name of the Cluster

<hostname_of_Grafana_host> = FullyqualifiedDomain Name of the node where Grafana has to be deleted.
