problems with python client
I'm trying to use the python client to do a POC with Ambari, but following the examples in the docs has led me to a problem that I can't figure out. I set it up with the "Quick Start Guide" and the Ambari UI works perfectly on the 3-node cluster I have running on my machine. I'm just attempting a basic create server call, but the server gives me a 400: Bad Request response no matter what I try. Can anyone shed light on this? I turned on DEBUG logging on the server, but there was still no actual details as to the problem in the logs.
This is my code:
from ambari_client.ambari_api import AmbariClient
client = AmbariClient("c6401.ambari.apache.org", 8080, "admin", "admin", version=1)
mycluster = client.create_cluster("testcluster", "HDP-2.1")
Any ideas?
Greg

Hi Greg
I have already supported add X-Requested-By header in the client.
https://issues.apache.org/jira/browse/AMBARI-5663
Unfortunately i forgot to update the wiki. I will update the wiki now.
btw thanks for looking into client.Let us know if you find issues, we would
be happy to help you.

Thanks Dmitry. Adding that header does indeed get past the problem. If nobody else gets to it, I'll get a pull request together for the change.

A quick search through python ambari-client sources did not find any usages
of X-Requested-By header that is used for CSRF protection in Ambari.
e.g.
/usr/bin/curl -X DELETE -H "X-Requested-By:anything" -u admin:admin
http://dev01.hortonworks.com:8080/api/v1/clusters/c1/services/MAPREDUCE
At the same time, groovy client contains references of this header. So
maybe python client needs update.

Or you may try adding http_header parameter during AmbariClient
construction.
