log files on the cluster?
Hi,
it is probably described somewhere in the manuals, but
1. Where are the log files, especially those that show my
System.out.println() and errors; and
2. Do I need to log in to every machine on the cluster?
Thank you,
Mark

Hey,
If you're running Cloudera's Distribution for Hadoop (CDH) and looking for
log files, you may find the following blog post useful:
