Subject Re: Changing ambari-server web port
Date Thu, 06 Mar 2014 07:32:42 GMT
Hi Gunnar,
If your node has multiple IP addresses, maybe the curl command is going
against the wrong IP address?
Can you please try "curl --user admin:admin
http://127.0.0.1:8000/api/v1/clusters/<http://node10.usa.hp.com:8000/api/v1/clusters/>"
from that host.

Also, you will need the following header added to your curl command (to
prevent CSRFs): -H "X-Requested-By:ambari"
Regards,
Srimanth
