I just downloaded the new logstash version (5.2.1), and after starting it I noticed a warning message saying that log4j needs to be initialized properly. I also noticed that plugins like kafka, beats, etc, were not emitting any output log... I used this very simple command to reproduce the problem…

Fresh logstash 5.2 install gives log4j warnings and no logging from plugins
