在Fedora 23上搭建hadoop-0.20

　　参考http://blog.csdn.net/ab198604/article/details/8250461

　　Fedora关闭防火墙的命令如下:

　　systemctl stop firewalld.service

 

　　禁用IPv6

Step 1: add this rule in /etc/sysctl.conf : net.ipv6.conf.all.disable_ipv6=1

Step 2: add this rule in /etc/sysconfig/network: NETWORKING_IPV6=no

Step 3: add this setting for each nic X (X is the corresponding number for each nic) in /etc/sysconfig/network-scripts/ifcfg-ethX:IPV6INIT=no
