Hi Bajaj, Abhinav,

Could you share the start-command of jobmanager and taskmanager. If it is started correctly, we
will have a the following jvm options.

-Dlog.file=/path/of/taskmanager.log -Dlogback.configurationFile=file:///path/of/logback.xml



Best,
Yang

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.
