Wrong log4j properties file picked up by Kafka start script

[Sigurd Knippenberg]

When I run the following command: 

/usr/bin/kafka-server-start /etc/kafka/server.properties

It picks up the /etc/kafka/tools-log4j.properties file and not the /etc/kafka/log4j.properties file.

I think that is because the following KAFKA_LOG4J_OPTS variable is set in the /usr/bin/kafka-server-start script without the export statement:

if [ "x$KAFKA_LOG4J_OPTS" = "x" ]; then

  if [ -e "/etc/kafka/log4j.properties" ]; then # Normal install layout

    KAFKA_LOG4J_OPTS="-Dlog4j.configuration=file:/etc/kafka/log4j.properties"

  elif [ -e "$base_dir/../etc/kafka/log4j.properties" ]; then # Simple zip file layout

    KAFKA_LOG4J_OPTS="-Dlog4j.configuration=file:$base_dir/../etc/kafka/log4j.properties"

  else # Fallback to normal default

    KAFKA_LOG4J_OPTS="-Dlog4j.configuration=file:$base_dir/config/log4j.properties"

  fi

fi

It works fine like this:

if [ "x$KAFKA_LOG4J_OPTS" = "x" ]; then

  if [ -e "/etc/kafka/log4j.properties" ]; then # Normal install layout

    export KAFKA_LOG4J_OPTS="-Dlog4j.configuration=file:/etc/kafka/log4j.properties"

  elif [ -e "$base_dir/../etc/kafka/log4j.properties" ]; then # Simple zip file layout

    export KAFKA_LOG4J_OPTS="-Dlog4j.configuration=file:$base_dir/../etc/kafka/log4j.properties"

  else # Fallback to normal default

    export KAFKA_LOG4J_OPTS="-Dlog4j.configuration=file:$base_dir/config/log4j.properties"

  fi

fi

I assume this script is coming from Confluent since the script in Kafka's GitHub (https://github.com/apache/kafka/blob/0.8.2/bin/kafka-server-start.sh) is different (and it does contain the export statement).

Thanks for reporting this. Yes, that seems like a bug. We will fix it in the next release.
