Hello,
we use logback instead of log4j and get this error after upgrading Flink to
1.20. It seems that 1.20 does not support logback 1.2.13. We cannot upgrade
because, as documentation states, "Logback 1.3+ requires SLF4J 2, which is
currently not supported". We see that the 1.20 impleme
My Flink app uses logback for logging, when submitting it from the operator

Sorry for the late reply.
Flink clients will ship the log4j-console.properties and
logback-console.xml via K8s ConfigMap and then mount to
JobManager/TaskManager pod.
So if you want to update the log settings or using logback, all you need is
to update the client-local files.

Hi Sharon
Thanks a lot. I just updated the files (flink-conf.yaml and
logback-console.xml) in the local conf folder and it worked as expected.
Thanks & Regards

MERAS Plugins

which allows me to specify a local folder which contains the logback config
using file `logback-console.xml`. The content of the file is then used to
create the config map.
Hope it helps.

Did you have removed the log4j related jars in the $FLINK_HOME/lib
directory?

Could you please check that the environment variables have been properly
set?
Maybe you could tunnel into the Kubernetes pod via "kubectl exec" and do
such verification.

That's why the logback does not log anything. Log4j implementation is
slightly different as by default it does not follow changes to the
System#setOut. It buffers the original System.out. It has an option

Hi Bajaj,
I am not entirely sure what is the actual issue you are seeking help,
but let me comment on your observations.

If you log to the console from the main method this is an expected
behavior in both cases (log4j, logback). The std out is being

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 Fli

launch your flink jobs they will be clones with the correct files and happy

aren't using them so :shrug:

Has anyone configured AWS EMR’s flavour of Flink to use Logback (more
specifically with the logstash encoder, which would require additional jars
on the classpath)
Or is there an alternative way people are using to send the logs to a
service like Datadog
Thanks in advance

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]

Hi all,
I have a Flink cluster (1.4.0) built from flink's docker image, with 1 job

as far as the cluster configurations goes, seems alright.

I have a single node Flink instance which has the required jars for logback
in the lib folder (logback-classic.jar, logback-core.jar,
log4j-over-slf4j.jar). I have removed the jars for log4j from the lib

correctly

Even though I have executed the same code with intelliJ and works fine?
The only difference is that intelliJ is using log4j and the other application
is using logback.
Moreover, the snippet is quite simple, it does not reference any user class
