Cassandra 2.0.1
OpsCenter 3.2.2
Java 1.7.0_25
RHEL 6.4

This is a new test cluster with just three nodes, two seed nodes, SSL turned 
off, and GossipingPropertyFileSnitch. Pretty much out of the box environment, 
with both Cassandra and OpsCenter via DataStax yum repository.

Cassandra seems fine, and OpsCenter is installed on a seed node. The OpsCenter 
gui comes up, but is unable to connect to the cluster, I get this error

INFO: Starting factory 
<opscenterd.ThriftService.NoReconnectCassandraClientFactory instance at 
0x2440290>
INFO: <twisted.internet.tcp.Connector instance at 0x24402d8> will retry in 2 
seconds
DEBUG: Problem while pinging node: Traceback (most recent call last):
          File "/usr/lib/python2.6/site-packages/opscenterd/ThriftService.py", 
line 157, in checkThriftConnection
        UserError: User aborted connection: Shutdown requested.
WARN: ProcessingError while calling CreateClusterConfController: Unable to

INFO: Stopping factory 
<opscenterd.ThriftService.NoReconnectCassandraClientFactory instance at

Not getting very far troubleshooting it, any clues would be much appreciated. 
Should I try installing the OpsCenter agent manually maybe?

Many Thanks, Nigel
