Cannot register hosts in ambari for HDF

New Contributor

Two servers A and B are in NiFi Cluster (HDF 1.0) . I installed Ambari server with mpack in A to have enterprise features ( HDF 2.0 ) . Installed ambari agent and had setup password less SSH setup in A and B servers. I am trying to register A and B hosts in ambari (running on A) but I get "Host checks were skipped on 2 hosts that failed to register."

1. Anything wrong in what I did above? Please guide me if something went wrong.

2. I couldn't figure out why I get above error message even after setting up ipassword less SSH and installed ambari agent in both the servers.

thanks

From my experience, missing one of the pre-requisites for host settings is the cause.

See this: https://docs.hortonworks.com/HDPDocuments/HDF2/HDF-2.0.1/bk_ambari-installation/content/ch_getting_r...

Check once again all the pre-requisites mentioned in this document. It happened to me to believe that I did everything right, but going on it, I realized that it was one that I missed.
