Subject [jira] Commented: (PIG-18) Making Pig work with HOD 0.4 and hadoop 0.16

Craig Macdonald commented on PIG-18:
------------------------------------

Olga,

Apologies on the HOD confusion. I think you are privy to more information than me!

For SSH tunneling, i understand your Hadoop cluster is behind a SSH gateway. Is it also SOCKS
accessible? 

An easier option would be: 
Run HOD locally, use ssh wrappers to run the Torque tools, and tell Java to use the SOCKS
server for all socket connections, i.e. the Hadoop connections.

For the SSH tunneling of the Torque commands, create this executable script in your path:
{noformat}
#!/bin/bash
REMOTEPBSPATH=/usr/local/bin
ssh sshgateway $REMOTEPBSPATH/$0 "$@"
{noformat}

and symlink qsub and qstat to it.

See http://java.sun.com/javase/6/docs/technotes/guides/net/proxies.html for how to configure
Java to use SOCKS.
A simple SOCKS server is http://ss5.sourceforge.net

Overall, this would keep the Pig codebase more lightweight.
