Query a cluster to determine its services? #21

Closed snowch closed 8 years ago

snowch commented 8 years ago

At the moment, a test is run even if the cluster doesn't have the service enabled. An example of this is running BigX tests on a Basic (paygo) cluster. It would be much nicer if we could skip a test if that cluster doesn't support that test.

Is there some metadata we can query on the cluster to:

the type of cluster, basic or standard
detect which services are available

I think for this, could query ambari rest api to see if service is present e.g

https://:/api/v1/clusters//services

Then check json object to see if service is there or not.

Thanks @pregazzoni

See new ambari example I added. It lists all services on given cluster.
