1. 目录/opt/hadoop/etc/hadoop
core-site.xml
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://mip:9000</value>
</property>
</configuration>
mip：在主节点的mip就是自己的ip，而所有从节点的mip是主节点的ip。
9000：主节点和从节点配置的端口都是9000
hdfs-site.xml
<configuration>
<property>
<name>dfs.nameservices</name>
<value>hadoop-cluster</value>
</property>
<property>
<name>dfs.replication</name>
<value>1</value>

<property>
<name>dfs.namenode.name.dir</name>
<value>file:///data/hadoop/hdfs/nn</value>

</property>
<property>
<name>dfs.datanode.data.dir</name>
<value>file:///data/hadoop/hdfs/dn</value>
</property>
</configuration>
dfs.nameservices：在一个全分布式集群大众集群当中这个的value要相同
mapred-site.xml
<configuration>
<property>
<!-指定Mapreduce运行在yarn上-->
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
</configuration>
yarn-site.xml
<configuration>
<!-- 指定ResourceManager的地址-->
<property>
<name>yarn.resourcemanager.hostname</name>
<value>mip</value>
</property>
<!-- 指定reducer获取数据的方式-->
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce_shuffle</value>
</property>
<property>
<name>yarn.nodemanager.local-dirs</name>
<value>file:///data/hadoop/yarn/nm</value>

</configuration>
创建目录
mkdir -p /data/hadoop/hdfs/nn mkdir -p /data/hadoop/hdfs/dn mkdir -p /data/hadoop/hdfs/snn mkdir -p /data/hadoop/yarn/nm
一定要设置成：chmod -R 777 /data
hdfs启动 ./hadoop-daemon.sh start namenode
yarn启动 ./yarn-daemon.sh start resourcemanager
