Where does System.out.println() go?
Hi,
when I run Hadoop in pseudo-distributed mode, I can't find the log which
System.out.println() goes.
When I run in the IDE, I see it. When I run on EC2, it's part of the output
logs. But here - do I need to set something up?
Thank you,
Mark

Hi, sysout for Map Reduce should be visible in 50030 task tracker UI against
the individual Map Reduce tasks for executed JOB. This UI anyways uses the
individual logs created against each attempt in logs/userlogs/attempt****
folders.
