Some useful methods
Code Block language python title Show all clusters in Ambari firstline 1 linenumbers true all_clusters = client.get_all_clusters() print all_clusters.to_json_dict() print all_clusters
Code Block language python title Show all hosts in Ambari firstline 1 linenumbers true all_hosts = client.get_all_hosts() print all_hosts print all_hosts.to_json_dict() print"\n"
We can also get the information of a specific cluster
