Hi Jinwei,
The way you are making a POST call to create a cluster looks correct.
A successful POST results in HTTP Status Code 201 ("Created").
Note that this only creates a Cluster resource, but there are many other
calls you would need to make in order to install a cluster (for example,
registering hosts to the cluster, creating services and its components,
assigning these components to specified hosts, creating and applying
configurations to the services, initiating installation of the services,
starting the services, etc).
We are only days away from having a release candidate of Ambari 1.2.0 ready.
I recommend you wait for the release candidate so that you will be able to
try installing a cluster via Ambari Web and observe all the API calls it
makes.
Thanks!
Yusaku
