Communication between Ambari-Instances

Hi,

I have seen, that you can add a remote Cluster in Ambari. My question is: How communicate the Ambari with the other Ambari-Instances. Use Ambari the REST-API for they own?

Best Regards

Yes When we configure the "Remote Cluster" then in that case we will have to know 2 things about the remote cluster:

1. The cluster API URI:

http://$REMOTE_AMBARI_HOSTNAME:8080/api/v1/clusters/$CLUSTER_NAME

2. The Remote Cluster Ambari Admin Credentials ( like admin/admin)

Once we provide the above two details in our Remote Cluster configuration then we can extract almost every details from the remote cluster Like various configurations/resources/statistics ...etc.

Ambari Makes use of the Rest APIs fully to communicate with the remote cluster. https://docs.hortonworks.com/HDPDocuments/Ambari-2.5.1.0/bk_ambari-administration/content/registering_remote_clusters.html
