There's another open thread on a similar situation but I'm not quite sure this is completely related, so I'm opening a new one.
Is there a particular setting that has to be used when logging from an application that is running in YARN? I quickly put together a simple application that reads from and writes to Kafka, starting from the Maven Java archetype. I didn't edit the log4j.properties coming with the archetype, so it's currently using a ConsoleAppender, but I'm not sure on how I should edit it in order to make it appear in the YARN aggregate logs; as of now, yarn logs just show the TaskManager and JobManager logs, with no signs of my logs appearing on them. Should I look elsewhere. In the application I use SLF4J, like this: private static final Logger logger = LoggerFactory.getLogger(Job.class); To make sure I'm not just skipping the points where I log, I put error level logs at the very first line of my application. Still nothing. -- BR, Stefano Baghino Software Engineer @ Radicalbit
