在中，Hadoop 3.1.0 namenode运行正常，但datanode无法运行，显示以下消息:

我遇到了同样的问题，我不得不替换bin文件夹引用Hadoop-3.1.2: Datanode and Nodemanager shuts down中的一些二进制文件，也对配置文件中的某些配置文件进行了如下更改:
1. Edit file [core-site.xml]
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://0.0.0.0:19000</value>
</property>
</configuration>
2. Edit file hdfs-site.xml
<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
<property>
<name>dfs.namenode.dir</name>
<value>file:///C:/hadoop-3.1.0/data/namenode</value>
</property>
<property>
<name>dfs.datanode.dir</name>
<value>file:///C:/hadoop-3.1.0/data/datanode</value>
</property>
</configuration>
3. Edit file workers
localhost
4. Edit file mapred-site.xml
<configuration>
<property>
<name>mapreduce.job.user.name</name>
<value>%USERNAME%</value>
</property>
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
<property>
<name>yarn.apps.stagingDir</name>
<value>/user/%USERNAME%/staging</value>
</property>
<property>
<name>mapreduce.jobtracker.address</name>
<value>local</value>
</property>
</configuration>
5. Edit file yarn-site.xml
<configuration>
<property>
<name>yarn.server.resourcemanager.address</name>
<value>0.0.0.0:8020</value>
</property>
<property>
<name>yarn.server.resourcemanager.application.expiry.interval</name>

关于hadoop - 在Hadoop 3.1.0中，namenode正常运行，但datanode无效，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58840500/
