Ryan P updated KAFKA-3754:
--------------------------
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= <number of files>
-XX:GCLogFileSize=<size of files>
