I'm trying to profile an application remotely. VisualVM appears to be a good tool, currently I'm using version 1.3.8. I've installed it on my local machine.
The app I need to profile is on an Amazon EMR cluster - I'm using the Master EC2 node to connect. (I think this is correct)
I've followed a small tutorial Tut and made some progress. I added the ports to the security group so they are open and then checked this using a web interface. VisualVM wouldn't connect. I then disabled iptables on the ec2 instance thnking perhaps there were still some firewall issues but still unabel to connect.
When I run the jstad command from the terminal there is no feedback -I'm not sure if there should be, it doesn't error but just sits there.
command is: ./jstatd -J-Djava.security.policy=jstatd.all.policy
where the policy is one form the tutorial, without this I received a write exception.
I'd very much like to get this working and any help is hugely appreciated, thanks!
