-----------------------------

             Summary: Kafka default -Xloggc settings should include GC log rotation flags
                 Key: KAFKA-3754
                 URL: https://issues.apache.org/jira/browse/KAFKA-3754
             Project: Kafka
          Issue Type: Bug
            Reporter: 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>
