I am using the log4j.properties in My Selenium Package.
Every Time I run the Module the below 3 Lines are always been added in the Console and the Applications.log file.
log4j:WARN No appenders could be found for logger (org.apache.http.client.protocol.RequestAddCookies).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
For Reference, below is the log4j.properties Code:
#Application Logs
log4j.logger.devpinoyLogger = DEBUG,dest1
log4j.appender.dest1=org.apache.log4j.RollingFileAppender
log4j.appender.dest1.maxFileSize= 5000KB
log4j.appender.dest1.maxBackupIndex=3
log4j.appender.dest1.layout=org.apache.log4j.PatternLayout
log4j.appender.dest1.layout.ConversionPattern=%d{dd/MM/YYYY HH:mm:ss} %m%n
log4j.appender.dest1.File=D:\\Automation\\src\\Logs\\Application.log
#do not append the old file .Create a new log File everytime
log4j.appender.dest1.Append=false
Please let me know what needs to be change in order to remove the 3 lines of Warnings from the console output and Application logs.
Please include the following snippet to your code:
System.setProperty("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.Jdk14Logger");
Hope this helps!
This will resolve your errors and the message appears in the console:
System.setProperty("org.apache.commons.logging.Log",
"org.apache.commons.logging.impl.Jdk14Logger");

I have submitted the following command
$java -cp spark-kafka-fraud-detection-assembly-1.0.jar com.jcalc.feed.CCStreamingFeed 50
Its seems like started executing.I can see the following things in my console
log4j:WARN No appenders could be found for logger (org.apache.hadoop.metrics2.lib.MutableMetricsFactory).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
Its remain in same state for long time .Nothing got executed expect the above three lines . Can any one help me .Thanks!
How can I write logs to stderr, stdout, and syslog in Hadoop 2.2 or higher? I tried to use log.info, log.error, System.out.println, and System.err.println but I only got the following from the log director:
stderr : Total file length is 222 bytes. log4j:WARN No appenders could
be found for logger (org.apache.hadoop.ipc.Server). log4j:WARN Please
initialize the log4j system properly. log4j:WARN See
http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
stdout : Total file length is 0 bytes.
syslog : Total file length is 34828 bytes.
(I searched and can't find my contents.)
It's a Java problem rather an Hadoop one, you did not correctly configured the Log4J.
log4j:WARN No appenders could be found for logger
on cloudera you can find the log4j.properties into the config dir of each module.
I've been trying to change the log level on userlogs i.e the files that appear under /var/log/hadoop-yarn/userlogs/application_<id>/container_<id> on CDH 5.2.1. However, no matter what I try, only INFO level logs will appear. I want to enable TRACE level logs for debugging.
Things I have tried so far:
Setting all loggers to TRACE level in /etc/hadoop/conf/log4j.properties.
Setting mapreduce.map.log.level and mapreduce.reduce.log.level in mapred-site.xml.
Setting mapreduce.map.log.level and mapreduce.reduce.log.level in the job configuration before submitting it.
Including a log4j.properties in my job jar file that sets the root Log4j logger to TRACE.
Modifying yarn-env.sh to specify YARN_ROOT_LOGGER=TRACE,console
None of these worked -- they didn't break anything, but they didn't have any effect on the log outputs under the userlogs directory. Modifying yarn-env.sh did cause the ResourceManager and NodeManager logs to enter trace level. Unfortunately these are not useful for my purpose.
I get the following error appearing in /var/log/hadoop-yarn/userlogs/application_<id>/container_<id>/stderr that may be relevant.
SLF4J: Class path contains multiple SLF4J bindings.

I don't understand why the log4j "no configuration" message would happen, given that there is a log4j.properties file at the root of the job jar file that specifies a root logger:
log4j.rootLogger=TRACE, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] %m%n
My code does not knowingly use SLF4J for logging, it purely uses Log4j.
The actual answer was to set yarn.app.mapreduce.am.log.level to the level you need, but, crucially, it needs to be set in the Hadoop job configuration at submission time. It cannot be set on the cluster globally. The cluster global will always default to INFO, as it is hardcoded.
Using container-log4j.properties alone will not work as YARN will override the log level value on the command line. See the method addLog4jSystemProperties of org.apache.hadoop.mapreduce.v2.util.MRApps and cross reference with org.apache.hadoop.mapreduce.MRJobConfig.
container-log4j.properties will indeed be honoured, but it can't override the level set by this property.
On CDH5.8, I am overwriting the application log level at job submission time. To modify the log level of the mappers and reducers, I had to specify them explicitly using a command like this:
hadoop jar my-mapreduce-job.jar -libjars ${LIBJARS} -Dyarn.app.mapreduce.am.log.level=DEBUG,console -Dmapreduce.map.log.level=DEBUG,console -Dmapreduce.reduce.log.level=DEBUG,console
The logs are written to the applications's syslog which can be browsed using the Yarn ResourceManager Web UI.
You should try to edit (or create if it does'nt exist) : /etc/hadoop/conf/container-log4j.properties.
You can see it with a simple ps aux : the command line includes -Dlog4j.configuration=container-log4j.properties.
I have a shell script test.sh with following contents :
echo " Running test.sh ..." | log
test_cp=./test/jar/*:./test/lib/*
test_main=com.test.TestApp
java -cp $test_cp $test_main | log
The relative paths used in the above file are correct as far as I understand. In this case, log4j jar is located at ./test/lib/ and the jar containing TestApp (test-app.jar) is located at ./test/jar/.
Now, the current scenario is that log4j.properties is packaged inside test-app.jar and all Java classes are using the log4j logger to create logs. The contents of log4j.properties are as follows :
log4j.rootLogger=ALL, CONSOLE, FILE
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d %-5p [%t] %c %M - %n%m%n
log4j.appender.FILE=org.apache.log4j.FileAppender
log4j.appender.FILE.File=test-app.log
log4j.appender.FILE.Append=false
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.ConversionPattern=%d %-5p [%t] %c %M - %n%m%n
We want to externalize the log4j.properties and move it outside the test-app.jar. For this, I have placed log4j.properties at ./test/properties/ and modified the shell script accordingly as follows :
echo " Running test.sh ..." | log
test_cp=./test/properties/*:./test/jar/*:./test/lib/*
test_main=com.test.TestApp
java -cp $test_cp $test_main | log
But I am getting the following error and no log file is generated, nor any logs get pronted on console.
log4j:WARN No appenders could be found for logger (com.noknok.util.PropertiesLoader).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
I also read somewhere on the Internet that this could be a Java classloader issue, so I have tried changing the sequence of different locations in classpath, placing log4j.properties in the directories that are already included in the classpath, etc.
But I am still getting the same error.
Thanks a lot for the help! Please get back if you need any other info.
Make sure log4j picks the correct log4j.properties file by using -Dlog4.debug
You can specify the config file by -Dlog4j.configuration=/path/to/file
I'm having the same issue described here: Log4j Warning while initializing?
My application has a log4j.properties that allows me to configure log4j.rootLogger=INFO, stdout correctly. However I still see:
log4j:WARN No appenders could be found for logger (org.jboss.logging).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
When running the application.
My log4j.properties currently reads:
log4j.rootLogger=INFO, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %t %c:%L - %m%n
#log4j.category.org.springframework=DEBUG,stdout
I've also tried adding the properties file to my config via:
#PropertySource(value= {
"classpath:/log4j.properties",
"classpath:/application.properties"
})
How can I make this error go away? I can toggle between DEBUG and INFO just fine via this file, so I know it's being read.
You can make this error go away by adding the line
log4j.logger.org.jboss.logging=INFO, stdout
to your log4j.properties.
I don't know why, but it seems like something sets the additivity of org.jboss.logging to false, causing it to ignore the root appender(s). So you can either find that magical spot or you add the the line above.
