I am trying to run Apache Kafka from git source but I am getting multiple SLF4J bindings warn which leads into a failure when using docker containers.
according to the documentation;
git clone --depth 1 --branch 3.1 https://github.com/apache/kafka.git
cd kafka
./gradlew clean
./gradlew dependencyUpdates
./gradlew jar -PscalaVersion=2.13.6
export UUID=$(./bin/kafka-storage.sh random-uuid); ./bin/kafka-storage.sh format -t $UUID -c ./config/kraft/server.properties
as a result I get:
SLF4J: Class path contains multiple SLF4J bindings.

any ideas on how to solve this issue?
The only issue here is that the kafka-storage script is loading the same jar multiple times.
The versions aren't different, so there's no actual problem. The bin/kafka-run-class script should be doing proper classpath isolation
You shouldn't need Gradle to run KRaft mode

Today I installed sqoop-1.4.6 in hadoop cluster, when I use sqoop import data to hdfs and it's ok, but when I see the sqoop log, it's only a little log and not print mapreduce to the log file. I think the reason from hadoop but I don't know how to resolve it.
The sqoop log info shows:

What could be the solution for this?
There is a problem (due to incompatibility) with SerDe jar, inside sandbox.
I had the same problem and after a few googles, I found a solution at
https://github.com/brandonswilson.
Here is what I did:
a-)removed the first line from hiveddl.sql
b-)changed line 34 to:
ROW FORMAT SERDE 'org.apache.hive.hcatalog.data.JsonSerDe'
That's it!
(After to run hive -f hiveddl.sql I got a problem at line 119:
-- FAILED: SemanticException Unrecognized file format in STORED AS clause: 'RCFILESE' --
Was: STORED AS RCFilese
I changed to: STORED AS RCFile
You could try to change before to run.)

SLF4J: Found binding in [jar:file:/home/cloudera/mahout-master/examples/target/dependency/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]
log4j:WARN No appenders could be found for logger (org.apache.mahout.driver.MahoutDriver).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
Please give me any solution Thanks.
After lots of hour searching i found this solution :
Create log4j.properties file
This is the main properties file having all runtime configuration used by log4j. This file will have appenders information, log level information and output file names for file appenders.
log4j.rootLogger=DEBUG,consoleAppender, fileAppender
log4j.appender.consoleAppender=org.apache.log4j.ConsoleAppender
log4j.appender.consoleAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.consoleAppender.layout.ConversionPattern=[%t] %-5p %c %x - %m%n
log4j.appender.fileAppender=org.apache.log4j.RollingFileAppender
log4j.appender.fileAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.fileAppender.layout.ConversionPattern=[%t] %-5p %c %x - %m%n
log4j.appender.fileAppender.File=demoApplication.log
This error was due to "log4j.properties" file missing you can find more info about this on : http://www.tutorialspoint.com/log4j/log4j_configuration.htm
