> Key: KAFKA-3754
> URL: https://issues.apache.org/jira/browse/KAFKA-3754
> Project: Kafka
> Issue Type: Bug
> Reporter: Ryan P
> Assignee: Ryan P
> Priority: Minor
>
> By default kafka-run-class.sh defines it's GC settings like so:
> KAFKA_GC_LOG_OPTS="-Xloggc:$LOG_DIR/$GC_LOG_FILE_NAME -verbose:gc
> -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps "
> This has to potential to generate incredibly large log files when left
> unmanaged.
> Instead it should include some sort of default GC log retention policy by
> adding the following flags:
> -XX:+UseGCLogFileRotation
> -XX:NumberOfGCLogFiles= <number of files>
> -XX:GCLogFileSize=<size of files>
> http://www.oracle.com/technetwork/java/javase/7u2-relnotes-1394228.html
> details these flags and their defaults
