1. disable selinux and iptables
service iptables stop
chkconfig iptables off; chkconfig ip6tables off
setenforce 0
sed -i 's,SELINUX=enforcing,SELINUX=disabled,g' /etc/selinux/config
2. disable ipv6
echo "net.ipv6.conf.all.disable_ipv6 = 1" >> /etc/sysctl.conf
sysctl -p
3. vi /etc/hosts to add all hosts FQDN, like below:
192.168.1.19 cm5.local cm5 archive.cloudera.com
192.168.1.20 master1.local master1 # HDFS NameNode
192.168.1.21 master2.local master2 # YARN ResourceManager
192.168.1.22 slave1.local slave1
192.168.1.23 slave2.local slave2
192.168.1.24 slave3.local slave3
192.168.1.25 client1.local client1
vi /etc/sysconfig/network to set FQDN
yum -y install ntp openssh-clients lzo
service ntpd start; chkconfig ntpd on
