Subject RE: OpsCenter not connecting to Cluster
Date Tue, 29 Oct 2013 18:29:33 GMT
Hi Nigel,

I've currently have a simular problem. However, it has only been reproduced on Ubuntu...
Are you using hsha as rpc_server_type?
is a guy with the same problem, showing how to reproduce.
I know the ppl of datastax are now investigating this, but no fix yet...

Kind regards,
Pieter Callewaert

Subject: OpsCenter not connecting to Cluster

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

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/", line 157, in
        UserError: User aborted connection: Shutdown requested.
WARN: ProcessingError while calling CreateClusterConfController: Unable to connect to cluster
INFO: Stopping factory <opscenterd.ThriftService.NoReconnectCassandraClientFactory instance
at 0x2440290> 

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

Many Thanks, Nigel
