Description

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= 10
-XX:GCLogFileSize=100M
