hadoop/hdfs/name处于不一致状态:存储目录(hadoop/hdfs/data /)不存在或无法访问

Question

我已尝试在stackoverflow上提供的关于此主题的所有不同解决方案,但没有帮助再次询问具体日志和详细信息

任何帮助表示赞赏

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文件夹的所有者.~/hadoop/hdfs/data&~/hadoop/hdfs/name文件夹都存在

并且两个文件夹的权限都设置为 755

在启动脚本之前成功格式化了namenode start-all.sh

这篇文章未能发布"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

以下是名称 - 节点日志文件的日志.

Answer 1

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>

感谢Erik的帮助.

Answer 2

按照以下步骤,

1.停止所有服务

2.格式化你的名字节点

3.删除数据节点目录

4.启动所有服务

Answer 3

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的权限

然后,

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>

如果不行,那么

stop-all.sh
start-all.sh
