分区考虑，不要使用LVM
root -- >40G

var -- >100G

swap -- 2倍系统内存

RAM -- >8GB

Master node:
RAID 10, dual Ethernet cards, dual power supplies, etc.

Slave node:
1. RAID is not necessary

2. HDFS分区, not using LVM
/etc/fstab -- ext3    defaults,noatime
挂载到/data/N/dfs/dn, for N=0,1,2... (one partition per disk)

on cloudera manager and all cluster nodes:

at least 3 Servers for ZooKeeper, 3 DataNodes for HDFS.

1.disable selinux and iptables
service iptables stop
chkconfig iptables off; chkconfig ip6tables off

setenforce 0
vi /etc/sysconfig/selinux
SELINUX=disabled

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
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

vi /etc/sysconfig/network to set FQDN

yum -y install ntp

service ntpd start; chkconfig ntpd on

reboot to confirm it‘s ok, double check cloudera manager web access

if it‘s ok

yum -y install cloudera-manager-agent
service cloudera-scm-agent start

5. on all cluster nodes
