                    Hi Arindam,
There was a validation error during cluster creation. Can you send contents of cluster_create.json ?Also, please attach output of:
$ http $SAVANNA_URL/images X-Auth-Token:$AUTH_TOKEN$ http $SAVANNA_URL/node-group-templates X-Auth-Token:$AUTH_TOKEN$ http $SAVANNA_URL/cluster-templates X-Auth-Token:$AUTH_TOKEN
Savanna debug logs also would be helpful. 

Please use *openstack-dev* as a mail-list for Savanna-related questions. Just prefix the subject with [Savanna].

I installed savanna from the git repository. I can create cluster but only with admin, when I try to create cluster with non-admin user it gives me an error:

    "error_code": 500,
    "error_message": "Error occurred during validation",
    "error_name": "INTERNAL_SERVER_ERROR"

The hadoop daemons are not started automatically so I could not run the test job.

when I try to start hadoop manually, it asks for a password. How to do it? Am I missing something?
