尝试从Apache Hadoop执行示例地图缩减程序。地图缩小作业运行时,下面有例外。试过hdfs dfs -chmod 777 /,但没有解决问题。

Win 8.1 + hadoop 2.7.0(从源代码构建)

  1. 以管理员模式运行命令提示符

  2. 执行etc \ hadoop \ hadoop-env.cmd

  3. 运行sbin \ start-dfs.cmd

  4. 运行sbin \ start-yarn.cmd

  5. 现在尝试运行你的工作

我最近遇到了完全相同的问题。我尝试重新格式化namenode,但它没有工作,我相信这不能永久解决问题。通过@aoetalks的参考,我通过查看本地组策略在Windows Server 2012 R2上解决了这个问题。

总之,请尝试以下步骤:

  1. 打开本地组策略(按Win+R打开"运行..." - 输入gpedit.msc
  2. 展开"计算机配置" - " Windows设置" - "安全设置" - "本地政策" - "用户权利分配"
  3. 找到"创建符号链接"在右侧,查看您的用户是否包含在内。如果没有,请将您的用户添加到其中。
  4. 这将在下次登录后生效,因此请注销并登录。
  5. 如果这仍然不起作用,也许是因为您使用的是管理员帐户。在这种情况下,您必须在同一目录中禁用User Account Control: Run all administrators in Admin Approval Mode(即组策略中的用户权限分配)然后重新启动计算机以使其生效。

我不知道错误的原因,但重新格式化NameNode 可以帮助我在 Windows 8 中解决它。

  1. 删除所有旧日志。清除文件夹 C:\ hadoop \ logs C:\ hadoop \ logs \ userlogs
  2. 清除文件夹 C:\ hadoop \ data \ dfs \ datanode C:\ hadoop \ data \ dfs \ namenode
    管理员模式下使用调用命令重新格式化NameNode:
    c:\hadoop\bin>hdfs namenode -format

有关解决方案,请参阅this,有关说明,请参见this。基本上,符号链接可能存在安全风险,UAC的设计会阻止用户(甚至是属于Administrators组的用户)创建符号链接,除非他们在提升模式下运行。

简而言之,请尝试重新格式化您的名称节点,并从提升的命令提示符启动Hadoop和所有Hadoop作业。

我遇到了和你一样的问题。我们通过检查java环境解决了这个问题。

  1. 选中java versionjavac version
  2. 确保群集中的每台计算机都具有相同的java环境

在Windows中,将hdfs-site.xml中的配置更改为

<configuration>
   <property>
       <name>dfs.replication</name>
       <value>1</value>
   </property>
   <property>
       <name>dfs.namenode.name.dir</name>
       <value>file:///C:/hadoop-2.7.2/data/namenode</value>
   </property>
   <property>
       <name>dfs.datanode.data.dir</name>
       <value>file:///C:/hadoop-2.7.2/data/datanode</value>
   </property>
</configuration>

以管理员模式打开cmd并运行命令:-

  • stop-all.cmd
  • hdfs namenode –format
  • start-all.cmd

,然后在管理员模式下运行最终的jar hadoop jar C:\ Hadoop_Demo \ wordCount \ target \ wordCount-0.0.1-SNAPSHOT.jar文件:/// C:/Hadoop/input.txt文件:/// C:/ Hadoop / output

我解决了同样的问题。当您运行“命令提示符”时,让我们“以管理员身份运行”。
