We are deploying CDH 5.10.0 through the Python client of cm_api in RHEL 6.8 hosted in Azure. We are receiving the following error during the configuring the CDH.

Connected to CM host on stt-mc-te.23qwyritdroeuryrw234jsdfjl.bx.internal.cloudapp.net and updated CM configuration

We checked with reverse DNS with the below python command and it gave the required results.

python -c "import socket; print socket.getfqdn(); print socket.gethostbyname(socket.getfqdn())"

Can someone please advice what might be the issue here.

hi @bkbasavaraju

in your environment, The CDH cluster is deploying on Azure VM?

cm_api.api_client.ApiException: Host 'stt-mc-te.23qwyritdroeuryrw234jsdfjl.bx.internal.cloudapp.net' not found. (error 404)

I think is the symptom for you question ,
you can set Public IP for your VM, and try run script again .
and can you show your code here?
in my company , is deploying the CDH cluster on Azure . we can learn from each other.
