Hey Sen, Is your code in the driver code or inside one of the tasks?
If it's in the tasks, the place you would expect these to be is in stdout file under <spark>/<appid>/work/[stdout/stderr]. Are you seeing at least stderr logs in that folder? If not then the tasks might not be running on the workers machines. If you see stderr but not stdout that's a bit of a puzzler since they both go through the same mechanism. - Patrick On Sun, Mar 9, 2014 at 2:32 PM, Sen, Ranjan [USA] <sen_ran...@bah.com> wrote: > Hi > I have some System.out.println in my Java code that is working ok in a local > environment.
