Cluster 1 - CDH4 >>> for s in api.get_cluster('Cluster 1 - CDH4').get_all_services(): ... print s.name ... hdfs1 mapreduce1 zookeeper1 hbase1 oozie1 yarn1 hue1 >>> Shell ----- After installing the `cm_api` Python package, you can use the API shell `cmps` (CM Python Shell): $ cmps -H <host> --user admin --password admin Welcome to the Cloudera Manager Console Select a cluster using 'show clusters' and 'use' cloudera> show clusters +------------------+ | CLUSTER NAME | +------------------+ | Cluster 1 - CDH4 | | Cluster 2 - CDH3 | +------------------+ cloudera> Please see the `SHELL_README.md` file for more.
