centos7进行hadoop伪分布式配置

接上篇文章https://blog.youkuaiyun.com/m0_49049914/article/details/120489822
1.配置core-site.xml
下面这段话放在configration中

<configuration>
    <property>
        <name>hadoop.tmp.dir</name>
        <value>file:/usr/local/hadoop/tmp</value>
        <description>Abase for other temporary directories.</description>
    </property>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://localhost:9000</value>
    </property>
</configuration>

这里的name仅仅只是一个name，value选择恰当的路径，一定要保证在保存完这个文本后把目录创建出来
2.配置hdfs-site.xml

<configuration>
    <property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
    <property>
        <name>dfs.namenode.name.dir</name>
        <value>file:/usr/local/hadoop/tmp/dfs/name</value>
    </property>
    <property>
        <name>dfs.datanode.data.dir</name>
        <value>file:/usr/local/hadoop/tmp/dfs/data</value>
    </property>
</configuration>

注意事项如上
3.格式化namenod
