Question

我一直试图在Windows 7上安装Hadoop一段时间了。我正在按照blog的说明进行操作。但遗憾的是，我无法运行Namenode。 hdfs-site.xml文件似乎存在问题，但我没有看到任何错误。请看看它

HDFS-site.xml中

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

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

以及我在命令提示符下运行hdfs namenode -format命令时遇到的错误日志：

C:\Users\ABC>hdfs namenode -format

并且有人可以指导我在这里做错了吗？

更新感谢@Binary Nerd正确设置。但现在我面临另一个问题，即使系统架构是32位，NameNode未启动并出现跟随错误（摘录）：

CreateProcess error=216, This version of %1 is not compatible with the version of
Windows you're running. Check your computer's system information to see whether
you need a x86 (32-bit) or x64 (64-bit) version of the program, and then contact
 the software publisher

Answer 1

看起来这是你得到的主要错误：

ERROR common.Util: Syntax error in URI F:\hadoop-2.7.2\data\namenode.

您已将其指定为：

<property>
    <name>dfs.namenode.name.dir</name>
    <value>F:\hadoop-2.7.2\data\namenode</value>
</property>

尝试的第一件事可能是使用与博客相同的格式（正斜杠）：

F:/hadoop-2.7.2/data/namenode

如果这没有帮助，您可以尝试将其设为有效URI：

file:///f:/hadoop-2.7.2/data/namenode

Answer 2

有点晚，但将来参考。

我的问题是我从教程中复制粘贴了hdfs-site.xml，并在此行添加了一个特殊字符，可能是换行符

<property><name>dfs.namenode.name.dir</name><value>/hadoop-
2.6.0/data/name</value><final>true</final></property>

所以只需去删除它

<property>
<name>dfs.namenode.name.dir</name><value>/hadoop-2.6.0/data/name</value><final>true</final>
</property>

这种安装问题是最糟糕的......他们只是劝阻你这么多

Answer 3

在hdfs-site.xml文件中，将F:\hadoop-2.7.2\data\namenode更改为file:/F:/hadoop-2.7.2/data/namenode

此错误将得到解决
