Hi all,   I had faced the same issue while kerberizing a HDP 3.1.0 cluster integrated with Iislon. The Ambari serer is a built on a Postgres DB cluster, hence it was NOT in the hadoop cluster. so it was NOT on the host list. [root@hdpdb ~]# curl -H "X-Requested-By: ambari" -u admin:admin "http://hdpdb.gz.local:8080/api/v1/clusters/Panyu/hosts"     I had to add the ambari server from adding host wizard and just install the clients. It worked around the "Host not found, hostname= xxxx" issue in my case.      Hope it will help, cheer!  ... View more
