@Kunal Kumar As you are getting the following error: NetUtil.py:96 - [Errno 8] _ssl.c:504: EOF occurred in violation of protocol . To solve this problem simply configure the Ambari Agent to use TLSv1.2 when communicating with the Ambari Server by editing each Ambari Agent’s /etc/ambari-agent/conf/ambari-agent.ini file and adding the following configuration property to the security section: [security] force_https_protocol=PROTOCOL_TLSv1_2 . Refer to a detailed explanation on this flag in the following article: https://community.hortonworks.com/articles/188269/javapython-updates-and-ambari-agent-tls-settings.html . Regarding your query "how to find /python/cert-verificatin.cfg" ? There is no need to set the verify=disable for this issue . However if you want to do it then you will have to manually create the mentioned file with the verify=disable.

@Kunal Kumar As we see the message as following in your "ambari-server.log" Host: hdpnode1.hortonworks.com Can not be determined . Which means your ambari server hosts "/etc/hosts" file does not have mapping for the "hdpnode1.hortonworks.com" Also as we see that you are using Sandbox which is suitable for a Single Node cluster only (as it runs inside a docker container hence all the ports of it are not exposed externally) Hence please make sure that from ambari agent host you can access ambari server host and port 8440 / 8080 Also the "/etc/hosts" file on ambari server host contains the IP and host mapping for "hdpnode1.hortonworks.com"
