Subject RE: HWI use on AWS/EMR
Date Fri, 18 Jan 2013 16:20:24 GMT
Thanks for the quick reponse Dean.

Confirmed that gives the same timeout.

Doesn't specifying http://<hostname>:9999<http://%3chostname%3e:9999> override
the requirement for port 80 being open?

Is ssh tunnelling the same as the process described by Ariel in the next reply?

Oops, I overlooked that you have the public domain name in your message. Can you surf to ?  If not, does HWI use port 80?
Is whatever port it uses blocked by EC2?

If it's blocked you can use ssh to tunnel the port through.

That's the internal hostname, not visible outside. Use the name like<>.
It's shown in the EMR console and the elastic-mapreduce script you might have used to launch
the cluster.

If that doesn't work, verify that port 80 is not blocked by default. That's certainly true
for ports 9XXX used by the JobTracker, etc.

I'm trying to get HWI running and accessible from an Amazon Web Services EMR instance. I've
hit a blocker early on though, and the documentation is less than illuminating. Can you share
any experiences you have had? Specifically, here's what I'm curious about.

- Running on AWS. I've created a Hive job flow on AWS, edited hive-default.xml (in /home/hadoop/.versions/hive-0.8.1/conf)
and changed the hive.hwi.war.file to lib/hive-hwi-0.8.1.war.
- HWI starts up fine, but when I try to connect with,
I get a timeout message, in Firefox it's "The connection has timed out - The server at<>
is taking too long to respond".

Has anyone successfully connected to HWI running on an AWS EMR instance? From the same browser
I can connect to HWI on a local Ubuntu box.
