Hi,

I am trying to leverage this tool to compare my two Hortonworks clusters. The script is not able to fetch the configurations and throwing below error. Any custom changes required for the script?

Exception:

ERROR: THIS SCRIPT IS NO LONGER SUPPORTED. PLEASE USE configs.py INSTEAD

As per the above suggestion, when i try to use the /var/lib/ambari-server/resources/scripts/configs.py python script i am getting below exception again.

Exception:

[*****@******** scripts]$ python configs.py --user=admin --password=***** --port=8443 --action=get --host=********** --cluster=test --config-type=yarn-site --file=/home/admvxb/configs/yarn_site_payload.json

File "configs.py", line 89, in do_request

raise Exception('Problem with accessing api. Reason: {0}'.format(exc))

Exception: Problem with accessing api. Reason: ''

Please help me to compare all my configuration between two of our clusters.

Thanks
