If you want to setup a multi node cluster then please refer to the following Hortonworks Youtube Video

Hadoop Series- Part1 Multinode Hadoop Cluster Installation using Ambari : https://www.youtube.com/watch?v=wHaVBoLwzwU

.

Regarding the failure which you posted in your last comment is happening due to:

  File "/var/lib/ambari-agent/tmp/os_check_type1546513757.py", line 40, in main    
raise Exception("Local OS is not compatible with cluster primary OS family. 
Please perform manual bootstrap on this host.")
Exception: Local OS is not compatible with cluster primary OS family. Please perform manual bootstrap on this host.

.

Looks like you are trying to register a new host which has slightly different OS version/type.

In that case we will suggest you to try using Manual Host installation & registration instead of doing it via Ambari UI. You can find the instructions to Manually Register Ambari Agenrt here:

https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.2.2/bk_ambari-administration/content/install_th...

The problem seems to be the incorrect "SSH Private Key". Based on screenshot "screenshot-from-2018-12-28-18-23-15.png" looks like you are pasting the "Public" key content there instead of "Private Key" of the host "hdpnode1.hortonworks.com"

For example the following will be the Private Key: "~/.ssh/id_rsa" adn the content of private key file looks something like following which BEGIN and END marks:

Example:

-----BEGIN RSA PRIVATE KEY-----
ANCDEFGHIJKLMNOPoCUhgGazht5XrPbvkcD
.......
QRSTUVWXYZasdoeruoijlcsd,fns,cjsdklfjo=
-----END RSA PRIVATE KEY-----

Usually Public key file name is "~/.ssh/id_rsa.pub"

Also the Ambari API call is showing 404 because you will need to replace the "$name" with your clustername. You can get your ambari cluster name using the following API call.
