Hi,

 

I am investigating a logging issue with Flink.

 

Setup

• Using Flink-1.7.1 using logback as suggested in Flink documentation here.
• 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.
