环境ubuntu,hadoop2.6,jdk7
排比句部署三台虚拟机一台namenode,两台datanode;/etc/hostname 都已经配置分布为master,node1,node2
/etc/hosts配置为：
27.0.0.1 localhost
127.0.1.1 ubuntu.localdomain ubuntu
The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
192.168.184.129 master
192.168.184.130 node1
192.168.184.131 node2
hadoop/etc/hadoo/slaves配置为造句：
node1
node2
core-site.xml配置为：
fs.defaultFS
hdfs://master:9000/
hadoop.tmp.dir
/home/yangwq/hadoop-2.6.0/temp
A base for other temporary directories.
hdfs-site.xml配置为：
dfs.replication
2
dfs.namenode.name.dir
file:/home/yangwq/hadoop-2.6.0/dfs/name
true
dfs.datanode.data.dir
file:/home/yangwq/hadoop-2.6.0/dfs/data
mapred-site.xml配置为：
mapreduce.framework.name
yarn
true
yarn-site.xml配置为：
yarn.nodemanager.aux-services
mapreduce_shuffle
yarn.nodemanager.aux-services.mapreduce.shuffle.class
org.apache.hadoop.mapred.ShuffleHandler
yarn.resourcemanager.hostname
master
在启动的时候node1节点的datanode一直无法启动，同时通过ssh登录各节点都是正常。
