Description

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):

    <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>

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.
