我已经尝试了stackoverflow提供的所有不同的解决方案，但是再次询问具体的日志和细节是毫无帮助的
感谢您的帮助
我的hadoop集群中有一个主节点和5个从节点。ubuntu用户和ubuntu组是 ~/Hadoop 文件夹和 ~/hadoop/hdfs/data & ~/hadoop/hdfs/name 文件夹存在
两个文件夹的权限都设置为 755 在启动脚本之前已成功格式化namenode start-all.sh 脚本无法启动“namenode”
它们在主节点上运行

ubuntu@master:~/hadoop/bin$ jps

7067 TaskTracker
6914 JobTracker
7237 Jps
6834 SecondaryNameNode
6682 DataNode

ubuntu@slave5:~/hadoop/bin$ jps

31438 TaskTracker
31581 Jps
31307 DataNode

下面是name节点日志文件中的日志。

遇到类似的问题，我格式化了namenode，然后启动了它

Hadoop namenode -format
hadoop-daemon.sh start namenode

在终端上运行这些命令

$ cd ~
$ mkdir -p mydata/hdfs/namenode
$ mkdir -p mydata/hdfs/datanode

授予目录755和755的权限
那么，
在conf/hdfs-site.xml中添加此属性

<property>
 <name>dfs.namenode.name.dir</name>
 <value>file:/home/hduser/mydata/hdfs/namenode</value>
</property>

<property>
 <name>dfs.datanode.data.dir</name>
 <value>file:/home/hduser/mydata/hdfs/datanode</value>
</property>

如果不起作用，那么

stop-all.sh
start-all.sh

从hdfs-site.xml文件中删除了“file:”
[错误的hdfs site.xml]

<property>
  <name>dfs.namenode.name.dir</name>
  <value>file:/home/hduser/mydata/hdfs/namenode</value>
  </property>
  <property>
  <name>dfs.datanode.data.dir</name>
  <value>file:/home/hduser/mydata/hdfs/datanode</value>
  </property>

[正确的hdfs site.xml]

<property>
  <name>dfs.namenode.name.dir</name>
  <value>/home/hduser/mydata/hdfs/namenode</value>
  </property>

  <property>
  <name>dfs.datanode.data.dir</name>
  <value>/home/hduser/mydata/hdfs/datanode</value>
  </property>

谢谢埃里克的帮助。

按照以下步骤操作，
1.停止所有服务
2.设置namenode的格式
3.删除数据节点目录
4.启动所有服务

1）将节点目录命名为所有者，并适当地指定chmod750
2）停止所有服务
3）使用hadoop namenode-format格式化namenode
4）将此添加到hdfs-site.xml

<property>
    <name>dfs.data.dir</name>
    <value>path/to/hadooptmpfolder/dfs/name/data</value> 
    <final>true</final> 
    </property> 
    <property> 
    <name>dfs.name.dir</name>
    <value>path/to/hadooptmpfolder/dfs/name</value> 
    <final>true</final> 
</property>

5）跑 hadoop namenode -format 添加 export PATH=$PATH:/usr/local/hadoop/bin/ 在~/.bashrc中，只要hadoop被解压，就在路径中添加它
