我们有hadoop集群，hadoop版本-2.6.x和ambari版本-2.5.0.x
在hadoop集群机器上是否应该禁用或启用avahi守护程序服务（master/workers/kafka）？
注意-我们想禁用此服务，特别是在数据节点计算机（worker）上，因为我们认为此服务可能是操作系统重新启动的原因，
目前，该服务已启用，并在hadoop集群中的所有计算机上运行
参考-https://www.systutorials.com/docs/linux/man/8-avahi-daemon/

service avahi-daemon status
Redirecting to /bin/systemctl status  avahi-daemon.service

注意-我想在/var/log/message文件中添加这样的内容，我们可以看到一百万条消息
