Configuring logback for my flink job

[Vishwas Siravara]

Hi,

I have a logback for my flink application which is packaged with the application fat jar. However when I submit my job from flink command line tool, I see that logback is set to 

-Dlogback.configurationFile=file:/data/flink-1.7.2/conf/logback.xml from the client log. 

As a result my application log ends up going to the client log. How can I change this behavior . I know a dirty fix is to add my logback config to the logback in /data/flink-1.7.2/conf/logback.xml . 

Any other suggestions on how I can have my application log to its configured appenders. 

Thanks,

Vishwas

Hi Vishwas,

If you mean to have your application logs to its configured appenders in client, i think you could use your own FLINK_CONF_DIR environment.

Otherwise, we could not update the log4j/logback configuration.[1]

My logback is a part of my application jar file, do you mean I should externalize it and pass set its location in FLINK_CONF_DIR ? 

like export FLINK_CONF_DIR=/home/was/

where I have logback.xml in /home/was/ ? 

Thanks,
