[jira] [Commented] (LOG4J2-1493) Cannot set all appenders as async
when including kafkaappender
[ https://issues.apache.org/jira/browse/LOG4J2-1493?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15407802#comment-15407802 ]
Mikael Ståldal commented on LOG4J2-1493:
----------------------------------------
I was able to reproduce this issue. However, I got the same error when using another appender. Can you try with Console or File appender and see what happen?
I suspect this is a problem with JsonLayout, and not with KafkaAppender.

> Environment: all
> Reporter: Jose Leon

> When I set this property:
> {noformat}
> -DLog4jContextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector
> {noformat}
> And use KafkaAppender like so:

> <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>

> <Root level="${sys:log.level}">
> <AppenderRef ref="kafka"/>
> </Root>
> </Loggers>
> </Configuration>
> {code}
> I get this stacktrace and no appenders work; with the goal being to get the KafkaAppender working at minimum
