Jose Leon created LOG4J2-1493:
---------------------------------
Summary: Cannot set all appenders as async when including
kafkaappender
Key: LOG4J2-1493
URL: https://issues.apache.org/jira/browse/LOG4J2-1493
Project: Log4j 2
Issue Type: Bug
Components: Appenders
Affects Versions: 2.6.2
Environment: all
Reporter: Jose Leon
When I set this property:
-DLog4jContextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector
And use KafkaAppender like so:
<?xml version="1.0" encoding="UTF-8" ?>
<Configuration status="warn">
<Appenders>
<Kafka name="kafka" topic="${sys:kafka.topic}">
<JsonLayout properties="true" locationInfo="true" complete="false"
compact="true" />
<Property name="bootstrap.servers">${sys:kafka.destinations}</Property>
<Property name="hostname">${sys:hostname}</Property>
<Property name="port">${sys:port}</Property>
<Property name="instance">${sys:instance}</Property>
</Kafka>
</Appenders>
<Loggers>
<Logger name="org.apache.kafka" level="INFO" />
<Root level="${sys:log.level}">
<AppenderRef ref="kafka"/>
</Root>
</Loggers>
</Configuration>
I get this stacktrace and no appenders work; with the goal being to get the
KafkaAppender working at minimum
