I agree with what you are saying here, but there is one other thing I would like to add. One of my motivations for starting work on Log4j 2 was that my employer had a need for a very flexible audit logging system. Most applications I am aware of do their auditing to a database. However, we w

Yes, Spark seems to have its own shutdown hook and it logs stuff from within there. If I put shutdownHook="disable" in my log4j2.xml, the problem goes away. But then I guess that Log4j is never shut down properly? On Wed, Jul 22, 2015 at 8:39 AM, Ralph Goers wrote: > The currentContext value in
