Hi,

I'm trying to add a Kafka appender in prlog4j2.xml but it results in a Java exception:

2021-05-06 07:49:08,434 main ERROR There was a problem initializing the LoggerContext using configuration file:XXXXXXXXXXXX/prlog4j2.xml org.apache.kafka.common.config.ConfigException: Invalid value org.apache.kafka.common.serialization.ByteArraySerializer for configuration key.serializer: Class org.apache.kafka.common.serialization.ByteArraySerializer could not be found. at org.apache.kafka.common.config.ConfigDef.parseType(ConfigDef.java:724) at org.apache.kafka.common.config.ConfigDef.parseValue(ConfigDef.java:469) at org.apache.kafka.common.config.ConfigDef.parse(ConfigDef.java:462)

What I did so far: 

•   Import kafka-log4j-appender-1.1.1.jar via Application->Distribution->Import (I kept all default values during Import)
•   Modify prlog4j2.xml to add this extra kafka appender
•   Restart server

I checked in pr_engineclasses table and both kafka-log4j-appender-1.1.1 and kafka-client-1.1.1 are available.

Modification in prlog4j2.xml are as follow:

• In Appenders part:    

    <Kafka name="KafkaAppender" topic="C1.log-MYTOPIC.001">         <Property name="bootstrap.servers">server1:yyyyy,server2.france.airfrance.fr:yyyy,server3.france.airfrance.fr:yyyy,server4.france.airfrance.fr:yyyy</Property>         </Kafka>

• In Loggers/asyncRoot part:

            <AppenderRef ref="KafkaAppender" level="INFO"/>  

Could anyone help me in finding why I can not use this Kafka appender ? 

Thanks !
