Subject Re: Question: how to run hadoop after the project split?
Date Tue, 11 Aug 2009 02:05:29 GMT
Hi Philip,

Tried the script.  It seems that the script could start a cluster but the web page did not
work.  Got the following error from the web interface:

HTTP ERROR: 404
/dfshealth.jsp
RequestURI=/dfshealth.jsp
Powered by Jetty://

Thanks,
Nicholas
