Subject INSTALL_FAILED status but no logs?
Date Wed, 03 Apr 2013 14:49:28 GMT

I am trying to create a cluster with HDFS programmatically by targeting the REST APIs in the
Ambari Server directly instead of using the Web frontend. I set the HDFS service state to
"INSTALLED" and I can see my host components entering the state "INSTALLING", but after a
while, they transition to "INSTALL_FAILED". The problem is that neither the ambari-server.log/out
nor the ambari-agent.log/out have any error messages.

I'm not sure if there are any other sources of information I should be looking at for errors,
or if I'm doing anything wrong when calling the REST APIs (all the API calls return successfully,
though). My test is a NodeJS program which I have attached in case anyone wants to take a
look at it. The ambari.js code is a supporting object model that enables easy calls to the

Does anyone know how can investigate why the state of my host components is ending up in INSTALL_FAILED?
