Welcome to Cloudera Manager API Client!
The python source is in the python directory. The Python client comes with a
cm_api Python client module, and examples on performing certain Hadoop cluster
administrative tasks using the Python client.
Here is a short snippet on using the cm_api Python client:
Python 2.7.2+ (default, Oct 4 2011, 20:06:09)
[GCC 4.6.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from cm_api.api_client import ApiResource
>>> api = ApiResource('rhel62-1.ent.cloudera.com', 7180, 'admin', 'admin')
>>> for h in api.get_all_hosts():
... print h.hostname
...
rhel62-2.ent.cloudera.com
rhel62-4.ent.cloudera.com
rhel62-3.ent.cloudera.com
rhel62-1.ent.cloudera.com
>>>
Another example: getting all the services in a cluster:
>>> for c in api.get_all_clusters():
... print c.name
...
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
>>>
After installing the cm_api Python package, you can use the API shell cmps
(CM Python Shell):
$ cmps -H <host> --user admin --password admin
