Is there a way to reload a log4j.properties file without stopping and starting the job server?
Hi!
The bundled log4j version (1.x) does not support that.
But you can replace the logging jars with those of a different framework
(like log4j 2.x), which supports changing the configuration without
stopping the application.
You don't need to rebuild flink, simply replace two jars in the
ile.

I read through the link you provided, Stephan. However, I am still confused. The instructions mention specific jar files for Logback, I am not sure which of the log4j 2.x jars I need to put in the the flink /lib directory. I tried various combinations of log4j-1.2-api-2.8.jar, log4j-slf4j-impl-2.8

Hi Nick,
the name of the "log4j-yarn-session.properties" file might be a bit
misleading. The file is just used for the YARN session client, running
locally.
The Job- and TaskManager are going to use the log4j.properties on the
cluster.

as an additional note: Flink is sending all files in the /lib folder to all
YARN containers. So you could place the XML file in "/lib" and override the
properties.

I assume you are using "*bin/flink run-application*" to submit a Flink
application to K8s cluster. Then you could simply
update your local log4j-console.properties, it will be shipped and mounted
to JobManager/TaskManager pods via ConfigMap.

Hi Ragini,
I think you actually have the opposite problem that your classpath contains
slf4j binding for log4j 1.2, which is no longer supported. Can you try
getting rid of the slf4j-log4j12 dependency?

Hey All
I'm Running Flink 1.14.2, it seems like it ignores system property
-Dlog4j.configurationFile and
falls back to /opt/flink/conf/log4j-console.properties
I enabled debug log for log4j2 ( -Dlog4j2.debug)
DEBUG StatusLogger Catching
java.io.FileNotFoundException: file:/opt/flink
I think the root cause is that we are using "flink-console.sh" to start the
JobManager/TaskManager process for native K8s integration after
FLINK-21128[1].
So it forces the log4j configuration name to be "log4j-console.properties".
[1]. https://issues.apache.org/jira/brows
org.apache.flink.kubernetes.kubeclient.parameters#hasLog4j returns
false then logging args are not added to startCommand.
1. why does the config dir gets cleaned once the cluster starts? Even when I
pushed log4j-console.properties to the expected location (/opt/flink/conf) ,
the directory includes only flink-conf.yaml.
2. I think
M/TM start
command, but the jobmanager.sh/taskmanager.sh. We do not
have the same logic in the "flink-console.sh".
Maybe we could introduce an environment for log configuration file name in
the "flink-console.sh". The default value could be
"log4j-console.properties"
ion, any idea why /opt/flink/conf gets cleaned (Only flink-conf.xml is
there).

Tamir

Changing the order of exec command makes sense to me. Would you please create a

The /opt/flink/conf is cleaned up because we are mounting the conf files from
