Hi,

do all nodes send their System.out.println() logs to the same place in
Hadoop job console? I don't see the mixture I would expect.

Thank you,
Mark

Hi Mark,

Are these print statements in the code of your job or the Hadoop
components (JobTracker, TaskTracker, etc.)?
Depending on where you place them, they might show up in the *.out
files that are created along with the log files (and not show up on
the console).

The statements are in my code. When I am running one node, I see them, but I
am not sure what happens when I am running more.

Do you see them in the ".out" files produced for each node?

Hey Mark,

You might find this blog post useful:
http://www.cloudera.com/blog/2009/09/apache-hadoop-log-files-where-to-find-them-in-cdh-and-what-info-they-contain/.
Given that it's a year old now, I expect it's out of date, but it might help
fill in some gaps.

Thanks,
Jeff
