Hi, I am trying to use cm python api, but it keeps failing out. Not sure, what is causing the issue. I get 404 error ! which I think represents object not found. Below is the code snippet import datetime
import getpass
import re
from cm_api.api_client import ApiResource
# Connection information.
host = 'XXXXXXXXXXXXXXXXXXXXXXX'
port = 7180
user = 'admin'
password = 'admin'
api = ApiResource(host, 7180, user, password)
# Finds the first YARN service in the first cluster.
cluster = api.get_all_clusters()[0] Its failing with Message Traceback (most recent call last):

cluster = api.get_all_clusters()[0]

cm_api.api_client.ApiException: (error 404)
Is it because of running python 2.6 ? I am running this on NameNode in my lab cluster(6 Node) that is running outside the production CM cluster. I am trying to use the API to connect to production cluster to fetch some metrics, but it keeps erroring out. Also, We have RM HA. Is there a way to find which node is my active Resource Manager ? and the URL for it ? without logging into CM ?
