Subject Re: Cannot access JobTracker GUI (port 50030) via web browser while running on Amazon EC2
Date Mon, 24 Oct 2011 20:37:46 GMT
I have the same issue and the output of "curl localhost:50030" is like
yours, and I'm running on a remote cluster on pesudo-distributed mode.
Can anyone help?

Thanks,
Mark
