Hi all. I've got a beginner question: Are there any best practices for how to do logging from a task? Essentially I want to log warning messages under certain conditions in my map and reduce tasks, and be able to review them later.
Is good old commons-logging using the TaskLogAppender the best way to solve this? I assume I'd have to configure it to log to StdErr to be able to see the log messages in the jobtracker webapp. The Reporter would be useful to track statistics but not for something like this. And the JobHistory class and history logs are intended for internal use only? Thanks a lot, Per
