[rabbitmq-discuss] RabbitMQ crashing upon starting with a clustering setup on EC2

[mdolian at engineyard.com]

I'm trying to cluster 2 nodes on EC2.  I have the erlang cookie in place on 
both instances and I verified this.  Both instances have the same 
rabbitmq.config file:

[
  {rabbit, [
    {cluster_nodes, 
['ip-10-114-25-195.ec2.internal','ip-10-158-69-124.ec2.internal']},
    {default_user, <<"guest">>},
    {default_pass, <<"guest">>}
  ]}
].

When I try to start up a single node, I get the following crash report in 
the log:  

=CRASH REPORT==== 6-Feb-2013::11:38:00 ===
  crasher:
    initial call: application_master:init/4
    pid: <0.112.0>
    registered_name: []
    exception exit: {bad_return,{{rabbit,start,[normal,[]]},
                                 {'EXIT',{rabbit,failure_during_boot}}}}
      in function  application_master:init/4
    ancestors: [<0.111.0>]
    messages: [{'EXIT',<0.114.0>,normal}]
    links: [<0.111.0>,<0.7.0>]
    dictionary: []
    trap_exit: true
    status: running
    heap_size: 2584
    stack_size: 24
    reductions: 245
  neighbours:

Everything works fine when I pull out the cluster_nodes configuration.  I'm 
not quite sure what I'm doing wrong.  I've also tried using rabbit1, 
rabbit2 as hostnames with /etc/hosts mapped to their internal IP address 
but ran into the same issue.  Any help would be greatly appreciated.

Thanks!
