THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
We can also get the information of a specific cluster
Code Block language python title Show a specific cluster in Ambari firstline 1 linenumbers true mycluster = client.get_cluster('cluster1') print mycluster print mycluster.to_json_dict() print"\n"
Tip mycluster is a ClusterModel object which has many useful methods.
Code Block language python title Show all hosts in the cluster firstline 1 linenumbers true clusters_hosts = mycluster.get_all_hosts() print clusters_hosts.to_json_dict() print clusters_hosts print"\n"
