Hi, I am investigating a logging issue with Flink.
Setup * Using Flink-1.7.1 using logback as suggested in Flink documentation here<https://ci.apache.org/projects/flink/flink-docs-stable/dev/best_practices.html#use-logback-when-running-flink-on-a-cluster>. * Submitting the Flink job from the Flink dashboard. Observations * Logs from main method(outside of job graph) do not show up in jobmanager logs. * Logs from the operators like map or custom operators do show up in the taskmanager logs. * Logs from main method do show up in jobmanager logs when using log4j in place of logback. Has anyone else noticed similar behavior or is this a known issue with logback integration in Flink? Any suggestions on potential workaround or fix? Appreciate your time and help. ~ Abhinav Bajaj
