Ok, thanks Ariel (and Dean in the next email!) I've set up PuTTY (v0.62) as follows: - EMR instance hostname in the Session/Host Name box (port left at 22, ok?) - In Connection/SSH/Auth I've added my private key file, downloaded from AWS ages for this account. - In Connection/SSH/Tunnels I've added 9999 in the Source Port box, proxy:9999 in the Destination box. Not sure if this is correct.
Hit the Open button, I can connect. (And I can see my changes in hive-default.xml, so I know I'm in the right place:) Then pointing my browser at http://localhost:9999 I get the same timeout again. Have I set up everything right? Also, following good advice I copied the config changes to hive-site.xml. How do I stop hive so I can restart with 'hive -service hwi' so that it picks up the new config?

Here is a website explaining how to set up port forwarding in putty (use port 9999): http://www.cs.uu.nl/technical/services/ssh/putty/puttyfw.html You can edit either hive-default or hive-site but the general practice is to store changes from the default configuration in hive-site.

We'll be accessing the HWI from Windows rather Linux desktops, so can you help me out with understanding how to carry out the port forwarding from a Windows environment? Currently I use WinSCP to initiate a connection to the EMR instance, then spawn a PuTTY session. The changes to the hive config look identical to what I've changed in my hive-default.xml. Does it make any difference which config file the changesare applied to (hive-default.xml vs hive-site.xml)?

When you connect to the master node using ssh you should use a command like the following: ssh -i /path/to/keyfile.pem -L 9999:localhost:9999 -l hadoop MASTER_HOSTNAME After you have connected, add the following to your hive/conf/hive-site.xml file: <property> <name>hive.hwi.war.file</name> <value>lib/hive-hwi-0.8.1.war</value> <description>This is the WAR file with the jsp content for Hive Web Interface</description> </property> Run this command to start up hwi: hive --service hwi And finally point your browser to: localhost:9999 That worked for me.

Can you surf to http://ec2-54-247-61-206.eu-west-1.compute.amazonaws.com ? 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. dean On Fri, Jan 18, 2013 at 10:06 AM, Dean Wampler <dean.wamp...@thinkbiganalytics.com<mailto:dean.wamp...@thinkbiganalytics.com>> wrote: That's the internal hostname, not visible outside. Use the name like ec2-NNN-NN-NN-NNN.compute-1.amazonaws.com<http://ec2-NNN-NN-NN-NNN.compute-1.amazonaws.com>. 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. dean On Fri, Jan 18, 2013 at 9:54 AM, Tony Burton <tbur...@sportingindex.com<mailto:tbur...@sportingindex.com>> wrote: Hi, 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 http://ip-XX-AAA-BBB-CCC.eu-west-1.compute.internal:9999/hwi, I get a timeout message, in Firefox it's "The connection has timed out - The server at ec2-54-247-61-206.eu-west-1.compute.amazonaws.com<http://ec2-54-247-61-206.eu-west-1.compute.amazonaws.com> 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. Thanks!
