Subject Re: Where is web interface in stand alone operation?
Date Wed, 10 Aug 2011 14:26:35 GMT

for further clarification. Are you running in standalone mode (1 JVM which runs everything)
or in pseudo-distributed mode (1 Machine, but with 5 JVMs)? With PDM, you can access the web
interfaces on ports 50030 and 50070. With SM, you should be able to at least to process monitoring
(unix time command, various trace commands)

mode how would I change the ports for the web interface because I have to connect to a remote
server which only allows certain ports to be accessed from the web?

just shows to run the jar example but how do you view job details? For example time to complete
etc. I know it will not be as detailed as the other modes but I wanted to compare the job
peformance in standalone vs pseudo mode. Thank you.
