Hi [~chesnay], we run flink jobs in "per job" mode on YARN,  first i don't see a way to change the configuration files through  REST API, secondly I think use API is a better way.
About the SLF4J API part，I totaly agree with you. Is it acceptable if we add an configuration to show we are using log4j2 or logback, so we can stay away from the SLF4J API.

> sometimes we may need to change loglevel to get more information to resolved bug, now we need to stop it and modify conf/log4j.properties and resubmit it ,i think it's better to add rest api to modify loglevel.
