Hi Chethan Well yes actually the issue was related to the DNS, actually the DNS was correctly configured and it was resolving the hostname but it seems that the reverse resolution was not working and it was blocking point. When I declared the hostnames in the /etc/hosts it worked normally. Regards

Dears, After installing CDP Base on premise, I'm deploying NIFI services. For this reason as recommanded, I created the Data Context and created compute cluster with two hosts and installed activated the Parcels CDH 7.1.5 by default a CFM 2.1.5, and when arriving to the Service selection (Custom Services) I don't see the NIFI services, all services belongs to the CDH parcels How can I get them ? Thank you in advance

Unfortunetly this error message was blocking the ZK Failover Controller, so I solved this issue by deleting all Zookeeper data and disabled Kerberos authentifcation and then I started zkFailover controller and I re enabled the Kerberos authentication on Zookeeper.

So normally it should be an internal traffic, but the firewall is showing external traffic to different IPs in different countries.
