Two options:

1. Either you can enable the passwordless ssh on ambari host and register it through ambari.

2. You can also manually install and register the Ambari agent on Ambari server hosts. see this https://docs.hortonworks.com/HDPDocuments/Ambari-2.2.0.0/bk_ambari_reference_guide/content/_install_...
