CM_API PYTHON. Services Dependencies.

[#1]

There is any way to specify or skip the services dependencies?

• Name of the ZooKeeper service that this YARN service instance depends on
• Name of the HDFS service that this YARN service instance depends on

When I am starting a cluster JUST using API, this is one error that I've found on YARN Service, and I can't format the NameNode just because of this. 

Any ideas?

Thanks

Hi awsbiddata,

There are some examples that you might find interesting, they show you how to use the CM API here;

a. to auto configure [0] OR

b. manually assign [1a,b]

# we will auto-assign roles; you can manually assign roles using the
# /clusters/{clusterName}/services/{serviceName}/role endpoint or by using
# ApiService.createRole()
cluster.auto_assign_roles()
cluster.auto_configure()
