Hi Naga, Thanks for getting back to me. So the reason this was failing was due to the fact I had stripped much of the content out of the blueprint (by setting each content field to be "content" : " ") , as I was having trouble passing this as data over ssh (via the chef knife command).
Effectively this was setting the content, and so the config, to be empty...... :-) I've realized that if I just remove these content directives, ambari will set these to the default values :-) I'm also base64 encoding the data and then decoding it in the chef recipe before performing the curl. Cheers!
