Description of problem:
RHQ Storage Node is not available after installation even though cassandra process is running.
agent.log contains:
2015-09-07 07:33:43,664 WARN  [ResourceContainer.invoker.daemon-1] (org.rhq.plugins.jmx.JMXServerComponent)- Failed to connect to ResourceType[id=0, name=RHQ Storage Node, plugin=RHQStorage, category=Server][RHQ Storage Node(fbr-rhq-test3.bc.jonqe.lab.eng.bos.redhat.com)]: Could not connect [service:jmx:rmi:///jndi/rmi://fbr-rhq-test3.bc.jonqe.lab.eng.bos.redhat.com:7299/jmxrmi] org.mc4j.ems.connection.EmsConnectException: IOException: Check service availability

Version-Release number of selected component (if applicable):
4.14.0-SNAPSHOT

How reproducible:
Always

Steps to Reproduce:
1. install rhq
2. navigate to RHQ Storage Node resource


Actual results:
Resource is down no child resources are discovered

Expected results:
The resource is up

Additional info:
I'm not sure if this is related but I noticed following exception in server.log from completely different setup (it's not visible on clean installation and I don't have repro steps):
