Hi folks
I am trying to set up a Riak cluster on EC2.
Each time I issue a command :
$ sudo riak-admin join [email protected]
It fails :
Attempting to restart script through sudo -u riak
Node [email protected] is not reachable!
Netstat on both the machines says the ports are running fine.
netstat -na | egrep '(8087|8098|8099)'
tcp 0 0 0.0.0.0:8098 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:8099 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:8087 0.0.0.0:* LISTEN
I can telnet to all the ports from each of the machine.
I have been pulling my hair for long but of no avail.
Can any one look and tell me what I am doing wrong.
Are there any debug logs where I can look at what is going wrong?
Is there any EC2 specific trick (like using public hostnames).
I am attaching my app.cfg file for reference.
Thanks
