在hadoop 3.1.0中 namenode 正在工作但是 datanode 不工作，显示以下消息：

STARTUP_MSG:   build = https://github.com/apache/hadoop -r 16b70619a24cdcf5d3b0fcf4b58ca77238ccbe6d; compiled by 'centos' on 2018-03-30T00:00Z

我也遇到了同样的问题，我不得不替换bin文件夹中的一些二进制文件参考hadoop-3.1.2:datanode和nodemanager关闭，我还对一些配置文件做了如下更改：-

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>
     <name>yarn.server.resourcemanager.application.expiry.interval</name>
     <value>60000</value>
   </property>
  <property>
     <name>yarn.server.nodemanager.address</name>
     <value>0.0.0.0:45454</value>
   </property>
  <property>
     <name>yarn.nodemanager.aux-services</name>
     <value>mapreduce_shuffle</value>
   </property>
  <property>
     <name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name>
     <value>org.apache.hadoop.mapred.ShuffleHandler</value>
   </property>
  <property>
     <name>yarn.server.nodemanager.remote-app-log-dir</name>
     <value>/app-logs</value>
   </property>
  <property>
     <name>yarn.nodemanager.log-dirs</name>
     <value>/dep/logs/userlogs</value>
   </property>
  <property>
     <name>yarn.server.mapreduce-appmanager.attempt-listener.bindAddress</name>
     <value>0.0.0.0</value>
   </property>
  <property>
     <name>yarn.server.mapreduce-appmanager.client-service.bindAddress</name>
     <value>0.0.0.0</value>
   </property>
  <property>
     <name>yarn.log-aggregation-enable</name>
     <value>true</value>
   </property>
  <property>
     <name>yarn.log-aggregation.retain-seconds</name>
     <value>-1</value>
   </property>
  <property>
     <name>yarn.application.classpath</name>
     <value>%HADOOP_CONF_DIR%,%HADOOP_COMMON_HOME%/share/hadoop/common/*,%HADOOP_COMMON_HOME%/share/hadoop/common/lib/*,%HADOOP_HDFS_HOME%/share/hadoop/hdfs/*,%HADOOP_HDFS_HOME%/share/hadoop/hdfs/lib/*,%HADOOP_MAPRED_HOME%/share/hadoop/mapreduce/*,%HADOOP_MAPRED_HOME%/share/hadoop/mapreduce/lib/*,%HADOOP_YARN_HOME%/share/hadoop/yarn/*,%HADOOP_YARN_HOME%/share/hadoop/yarn/lib/*</value>
   </property>

    </configuration>
