Hi @Alex M,

Referring to your error log it seems your agent registration is failing due to below error message :

("WARNING 2018-09-10 23:55:35,248 shell.py:822 - can not switch user for RUN_COMMAND.
WARNING 2018-09-10 23:55:35,352 shell.py:822 - can not switch user for RUN_COMMAND.

WARNING 2018-09-10 23:55:35,456 shell.py:822 - can not switch user for RUN_COMMAND.

Are you installing ambari as non-root user , have you given proper permissions as neccessary ?

Also can you please try to install and register ambari-agent mannually : https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.2.0/bk_ambari-administration/content/install_th...

and proceed using the add-host wizard.

Also i assume your node can do password less SSH to ip-10-40-145-25.ec2.internal which is your ambari-server ip. (even if its same host its required to have publickey added to authorized_keys )

cat id_rsa.pub >> authorized_keys

refer to : https://docs.hortonworks.com/HDPDocuments/Ambari-2.7.0.0/bk_ambari-installation/content/set_up_passw...

@Alex M

Have you tried running the command with sudo, are you running the installation like another user apart from root?

@Akhil S Naik

Thank you - running "cat id_rsa.pub >> authorized_keys" on Ambari Server did the trick
