配置环境变量

1.

vi  /home/wj/hadoop-2.7.7/etc/hadoop/hadoop-env.sh

修改export JAVA_HOME={$JAVA_HOME}

为 export  JAVA_HOME=/usr/java/jdk1.8.0.181/

2.

vi yarn-env.sh

找到#export JAVA_HOME=/home/y/libexec/jdk.1.6.0/

去掉#,改为

export JAVA_HOME=/usr/java/jdk1.8.0.181/

3.

vi core-site.xml

<configuration>
  <propoerty>
    <name>fs.defaultFS</name>
    <value>hdfs://master:9000</value>
  </property>
  <propoerty>
    <name>hadoop.tmp.dir</name>
    <value>/home/wj/hadoopdata</value>
  </property>
</configuration>

4.

vi hdfs-site.xml

<configuration>
<propery>
<name>dfs.replication</name>
<value>1</value>
</propery>
</configuration>

5. 

vi yarn-site.xml

<configuration>

<!-- Site specific YARN configuration properties -->
  <propery>
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce_shuffle</value> #洗牌,类似排序
  </propery>

 

  <propery>
    <name>yarn.resourcemanager.address</name>
    <value>master:18040</value>#主机端口

   </propery>

 

  <propery>
    <name>yarn.resourcemanager.scheduler.address</name>
    <value>master:18030</value>#调度端口

  </propery>

 

  <propery>

    <name>yarn.resourcemanager.resource-tracker.address</name>
    <value>master:18025</value>#跟踪端口

  </propery>

  <propery>
    <name>yarn.resourcemanager.admin.address</name>
    <value>master:18141</value>#管理操作端口

  </propery>

 

  <propery>
    <name>yarn.resourcemanager.webapp.address</name>#监控页面
    <value>master:18088</value>

  </propery>

</configuration>

6.

复制 mapred-site-template.xml

cp etc/hadoop/mapred-site-template.xml etc/hadoop/mapred-site.xml

vi mapred-site.xml

<configuration>

  <propery>
    <name>mapreduce.framework.name</name>
    <value>yarn</value>
  </propery>
</configuration>

7.

wj@master ~]$ pwd
/home/wj
[wj@master ~]$ vi ~/.bash_profile

#hadoop
export HADOOP_HOME=/home/wj/hadoop-2.7.7
export PATH=$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH

使配置生效
[wj@master ~]$ source .bash_profile
