Hadoop and HBase Web UIs on EC2

[Karthik Kambatla <kk...@cs.purdue.edu>]

Hi

Thanks all for bailing me out time and again.

I am using the HBase ec2 scripts to launch a cluster of machines on EC2
(hadoop 0.20.2 and hbase 0.20.6). I use my own AMI with hadoop and hbase
downloaded to the paths as specified in the EC2 scripts. Hadoop and HBase
work absolutely fine. However, I am unable to view the web UI at all.

I tunneled into the machine, and changed the foxyproxy settings to access
EC2 pages through the proxy. It doesn't throw an error, but shows a blank
page instead. I can't view page source either in my browser. The security
groups allow access to the ports (as security groups are created by the
scripts with required permissions).

I seem to be missing something very fundamental here. Any pointers?

Thanks
Karthik

Hi Jean

I have tried using both external and internal hostnames. I have also tried
localhost, after setting up the proxy to a particular port. When I login to
the master, and use links I am able to navigate the pages fine.

Thanks
Karthik

Are you using the external hostname or the internal one when trying to
see the pages? AFAIK it doesn't bind on the external ones.

Also, try to use "links" or any other text-based browser from the
machines to see the web pages on their internal hostnames.
