Many thanks for the pointers, Sid. I have started looking at the documentation
and I have been quite successful in calling the GET APIs. I am having trouble
locating the JSON payload some of the calls require, though.
For example, the POST call to /cluster/{clusterId}/configurations has a JavaDoc
comment with an example JSON payload, but when calling POST to
/cluster/{clusterId} I get a 400 error code with the message "Stack information
should be provided when creating a cluster".
I've tried to follow the code to see where the expected body is defined, but I
can't seem to find the right place. Can you point me towards it?
Thanks!
Ximo.

Asunto: Re: Some Ambari questions
Hi Ximo,
Here is a link to the Ambari wiki that should give you an idea of the design,
https://cwiki.apache.org/confluence/display/AMBARI/Ambari+Design
Currently the API docs are only GET calls. We are working on getting the
documentation up-to-date.
However, all of the calls made by the web UI are supported and if you want to
get a head start before the documentation is ready, you can actually mimic all
the calls made by the web UI and create a running cluster.
Best Regards,
Sid

Hello,
I am evaluating Ambari for a BigData platform my team is building, and it sure
looks like there's a bunch of sweet stuff in this project :) I am having some
problem finding documentation for the project, so maybe some of my questions
are answered somewhere and I just can't find the correct resource. Anyway,
here's the stuff I still don't understand about Ambari:
- What is the Ambari agent? Is there any document that describes the
general architecture of Ambari?
- How does the Web component communicate with the Ambari Server?
- Is the list in
https://github.com/apache/ambari/blob/trunk/ambari-server/docs/api/v1/index.md
the complete list of supported REST API calls?
Ambari looks like a really interesting project, but in my scenario the UI part
is not important since my team is looking for programmatic ways of deploying
Hadoop clusters. Does Ambari offer a programmatic surface to manage clusters
(set up Federated HDFS, add users, etc.)?
Thanks!
Ximo.
