As of Datatbricks runtime 11.0 with Spark 3.3.0, log4j has been upgraded to log4j2. I haven't seen official documentation for custom log support but this is what's been working for me.
Similar with log4j 1 support, you need a custom init script to run on the cluster and create a log4j2.properties file. This script might look something like:
#! /bin/bash
set -euxo pipefail
echo "Running on the driver? ${DB_IS_DRIVER}"
echo "Driver ip: ${DB_DRIVER_IP}"
cat >>/databricks/spark/dbconf/log4j/driver/log4j2.properties <<EOL

I use yarn to run my xxx.jar. As we know, syslog file will contain the log4j related logs. stdout file will contain some output like System.out.println(...). Blow is the some out put in stdout file:

So, i think the log4j related log will be saved in syslog file. But after run my xxx.jar in yarn, there is nothing in syslog, my xxx.jar also contains some code like: System.out.println("my demo");. And i can find the output "my demo" in stdout after run my xxx.jar.
So my question is why the log4j related output cann't been printed out? Is there any other configuration needed?
Got exactly same issue. (I use EMR-5.33, Oozie 5.2.0)
The logs are written to syslog if you set 0 to this property log4j.appender.CLA.totalLogFileSize
It gets the value from yarn.app.container.log.filesize config.
log4j.appender.CLA.totalLogFileSize=${yarn.app.container.log.filesize}
There is an Oozie ticket for that: https://issues.apache.org/jira/browse/OOZIE-3600
Getting below error while I am trying to print MqLog to elink.log via RulebaseCustomFunction (MDM 9)\
ERROR [stderr] (TIBCO EMS Session Dispatcher (895)) log4j:WARN No appenders could be found for logger (RulebaseCustomFunction).
ERROR [stderr] (TIBCO EMS Session Dispatcher (895)) log4j:WARN Please initialize the log4j system properly.
How to Configure in order to avoid above error?
Can somebody help me, please?
Default log4j configuration provided out-of-box does not have appender defined for RulebaseCustomFunction. However, you can always add new appender to ConfigValues.xml
Try adding below in "Logging" category-
<ConfValue description="The debugging logging level CustomRulebaseFunction" name="Logging Level for CustomRulebaseFunction" propname="log4j.logger.RulebaseCustomFunction" sinceVersion="8.0" visibility="All" isHotDeployable="true" isHidden="false">
<ConfString default="DEBUG,elink,error" value="DEBUG,elink,error"/>
</ConfValue>
Hi i am runnig the jar of this open source Ex-Crawler
But i always receive this error :
og4j:WARN No appenders could be found for logger (eu.medsea.mimeutil.TextMimeDetector).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info
The application you're running uses log4j to produce log files. And log4j needs a configuration file, usually named log4j.properties, to be available in the application's class path, in order to start properly.
This is sample of default configuration you might start with:
log4j.rootLogger=WARN, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.conversionPattern=%5p [%t] (%F:%L) - %m%n
I'm using the Cargo Maven plugin to deploy a WAR to a remote server, and I'm having problems. I'll probably create a second question for that problem, but this one is about overriding a Maven plugin's log4j configuration. Cargo uses JBoss' client libraries to ship stuff to JBoss servers (which I'm trying to do.) The JBoss library uses log4j. Cargo doesn't set up any sort of mapping layer that I know of.
So, essentially, log messages are occurring in the dependent library of a Maven plugin. I tried setting -Dlog4j.debug and got this information:
log4j: Trying to find [log4j.xml] using ClassRealm[plugin>org.codehaus.cargo:cargo-maven2-plugin:1.0.5, parent: ClassRealm[maven.api, parent: null]] class loader.

log4j: Finished configuring.
log4j:WARN No appenders could be found for logger (org.jnp.interfaces.TimedSocketFactory).
log4j:WARN Please initialize the log4j system properly.
Then I tried setting -Dlog4j.configuration=mylog4j.properties but got this:
log4j: Trying to find [mylog4j.properties] using context classloader ClassRealm[plugin>org.codehaus.cargo:cargo-maven2-plugin:1.0.5, parent: ClassRealm[maven.api, parent: null]].

log4j: Trying to find [mylog4j.properties] using ClassLoader.getSystemResource().
log4j: Could not find resource: [mylog4j.properties].
log4j:WARN No appenders could be found for logger (org.jnp.interfaces.TimedSocketFactory).
log4j:WARN Please initialize the log4j system properly.
It would appear that the log4j configuration file needs to be in the Maven plugin's classpath, but I don't know how to include random files there, only dependencies. I really want to set this information so that I can get debug information from the JBoss libraries in order to troubleshoot my problem.
With log4j.configuration you will set a resource string. Have a look at the log4j default initialization process and the examples.
If you use a syntax like this
-Dlog4j.configuration=mylog4j.properties
the file is expected in the classpath. But you can also use a syntax like this
-Dlog4j.configuration=file:/<path>/mylog4j.properties
to specify a fully qualified file location.
