分区考虑，不要使用LVM
root -- > 20G
swap -- 2倍系统内存
RAM -- >4GB
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, for N=0,1,2... (one partition per disk)
Cloudera repository:
http://archive.cloudera.com/cdh5/
http://archive-primary.cloudera.com/cm5/
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
