Using CDH 5, when I run my oozie workflow I no longer see log-statements from my mappers (log4j, slf4j). I even tried System.out.println - I still don't see the statements. Is there a setting I'm missing?
It turned out that the logs are still there except you need to manually point your browser to it. For example, clicking on a map-reduce action still opens the job log page something like (http://localhost:50030/jobdetails.jsp?jobid=job_201510061631_2112).
However to get the result for the actual job, I need to increment the jobid to job_201510061631_2113
