Hi, I use the Ambari-REST-API to query relevant metainformation of a Cluster. For this I have to pass a Username and a Password in the REST call. The user in the REST-call must have Admin-Privileges on the Cluster. Exist a Privileges/Role, lower than Admin, that I can grant a User to get access on the REST-API. I don’t want to modify Information in the Cluster. Best Regards Dominik ... View more

Hi, i have add two Ambari-Clusters in the remote configuration of another Ambari-Server. To manage these Clusters I write for my own an Ambari-View. To get the relevant Information I use the Ambari-REST-API. For the local-CLuster I know the username, Password and the domainname of the Cluster. But for the remote Cluster I dont want to manage this Information twice. Can I get this Information with the rest-API? I have admin-Privileges on the main-Ambari-Server. Best Regards Dominik ...
