Ivan Omar Olguin Torres commented on STORM-2617:
------------------------------------------------
This is a bug in log4j2:
https://issues.apache.org/jira/browse/LOG4J2-1804
The workaround works for me.
> log4j2 RollingFile rotation failing
> -----------------------------------
>
> Key: STORM-2617
> URL: https://issues.apache.org/jira/browse/STORM-2617
> Project: Apache Storm
> Issue Type: Bug
> Components: storm-server
> Affects Versions: 1.1.0
> Environment: NA
> Reporter: Daniel Kinon
> Priority: Minor
>
> I noticed that the default log rotation configuration isn't working as
> expected. A specific example is worker.log. Here is the default log4j2
> configuration for worker.log (log4j2/worker.xml):
> {code:xml}
> <RollingFile name="A1"
>
> fileName="${sys:workers.artifacts}/${sys:storm.id}/${sys:worker.port}/${sys:logfile.name}"
>
> filePattern="${sys:workers.artifacts}/${sys:storm.id}/${sys:worker.port}/${sys:logfile.name}.%i.gz">
> <PatternLayout>
> <pattern>${pattern}</pattern>
> </PatternLayout>
> <Policies>
> <SizeBasedTriggeringPolicy size="100 MB"/> <!-- Or every 100 MB
> -->
> </Policies>
> <DefaultRolloverStrategy max="9"/>
> </RollingFile>
> {code}
> Even thought the DefaultRolloverStrategy is set to 9, I only ever see
> worker.log and worker.log.1.gz. It seems like rotation is continually
> overwriting worker.log.1.gz . I expect this is either an issue with log4j2
> or an issue related to the RollingFileAppender and the associated filePattern.
