@Tom Burke

Please change the protocol to "https" in your case if you are using https for your ambari and then try this:

# curl -k -H "X-Requested-By: ambari" -u admin:admin "https://ambari.example.com:8443/api/v1/clusters/cluster-name/hosts?fields=Hosts/ip,Hosts/host_name" -o "/tmp/hosts.json"

.

Or atleast try to open the URL in the browser to see if it is working for you before trying with the Curl command and then once you knwo that the file which you are attaching is of any use or not then you can attach it

https://ambari.example.com:8443/api/v1/clusters/cluster-name/hosts?fields=Hosts/ip,Hosts/host_name

problem seems to be with this two-hosted DNS domain.....what if instead of using the ambari.example.com we use the corp.example.com all around with other hosts... so change their fqdn to ambari.corp.example.com, cpmpute1.corp.example.com I feel like spinning wheels trying to get it to work wiht short name,

abandoning this effort. was not getting anywhere as I think the ldaps in corp.example.com and machein hostname setup was causing all my issues., it is not a preferred setup anyhow I needed to correct so i renamed all cluster membre with corp....
