Log4j apperder

[Paweł Woźniak <pw...@man.poznan.pl>]

Hi!

I'm trying to test this fix: 
https://issues.apache.org/jira/browse/KAFKA-847 (and use Log4j Kafka 
appender) but I have some problems.

Here are my pom dependencies:

<dependency>
     <groupId>log4j</groupId>
     <artifactId>log4j</artifactId>
     <version>1.2.17</version>
</dependency>

<dependency>
     <groupId>org.apache.kafka</groupId>
     <artifactId>kafka_2.9.2</artifactId>
     <version>0.8.2.0</version>
</dependency>

and my log4j.properties file:

log4j.rootLogger=DEBUG, KAFKA
  
log4j.appender.KAFKA=kafka.producer.KafkaLog4jAppender
log4j.appender.KAFKA.layout=org.apache.log4j.EnhancedPatternLayout
log4j.appender.KAFKA.BrokerList=x.y.z:9092
log4j.appender.KAFKA.Topic=elog
log4j.appender.KAFKA.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

Now, when I try to run my main method (with single log.info(...)) i get 
in logs:

log4j: Parsing appender named "KAFKA".
log4j: Parsing layout options for "KAFKA".
log4j: Setting property [conversionPattern] to [%d{yyyy-MM-dd HH:mm:ss}

log4j: End of parsing for "KAFKA".

So it looks like there is still no appender (and layout) for logger. 
Application also trying to send message but is unable to do it.
The same application with downgraded kafka works (messages are delivered 
to kafka).

Can You help me somehow?

Regards.
