KAFKA日志管理

kafka启动后，会产生会多日志，经常会将磁盘撑爆。所以kafka日志清理很有必要

log4j.properties

该文件为kafka日志管理的配置文件，位于$KAFKA_HOME/config/log4j.properties

默认该配置文件中日志存放路径为$KAFKA_HOME/logs，可以修改为其他容量较大的数据盘，比如我自己设置为/data/kafka/logs

注意：如果只是改了这个配置，是不生效的，还需要修改脚本$KA_FKA_HOME/bin/kafka-run-class.sh，加入以下配置

LOG_DIR="/data/kafka/logs"

log4j.properties配置
