英文:
Hadoop namenode formatting windows - java.lang.UnsupportedOperationException
问题
以下是翻译好的内容:
我正在学校的数据库课程中,我的教授让我们使用Hadoop v3.2.1。在按照YouTube上的教程在Windows上安装时,我卡在了格式化namenode的部分。以下是在命令提示符中显示的内容:

我当时在遵循这个教程:在Windows上安装Hadoop,但到一半的时候我意识到它太旧了,于是切换到了这个教程:在Windows 10上安装Hadoop 3.2.0。
另外,我不确定这是否与我目前的问题有关,所以我会说明一下。当我跳到下一步并输入start-all时,资源管理器和节点管理器都出现错误。我把这些问题都放在一个问题里。

I am in a databasing class at school and my professor is having us work with hadoop v3.2.1. In following a youtube tutorial to install on windows, I am stuck on the formatting namenode part. this is what comes up in cmd:

and i was following this tutorial:
How to Install Hadoop on Windows until about halfway through when i realized it was too old and then switched to this one:
How to Install Hadoop 3.2.0 in Windows10
Also, I have no idea if this is related to my current problem, so I will say this. When I skip to the next step and type start-all, resource manager and node manager both error out. Figured I'd stuff it all into one question.
答案1
得分: 1
这是已经众所周知的,显然Hadoop 3.2.1在Windows 10上不能正常工作。我安装了3.2.0版本,现在正在取得进展。
英文:
It is well known apparently that hadoop 3.2.1 doesn't work on windows 10 properly. I installed 3.2.0 and am now making progress.
答案2
得分: 0
以下错误是Hadoop 3.2.1中的一个错误。
此问题将在下一个版本中解决。目前,您可以通过以下步骤临时修复它:
- 从此链接下载
hadoop-hdfs-3.2.1.jar
文件。 - 在文件夹
%HADOOP_HOME%\share\hadoop\hdfs
中将文件名hadoop-hdfs-3.2.1.jar
重命名为hadoop-hdfs-3.2.1.bak
。 - 将下载的
hadoop-hdfs-3.2.1.jar
复制到文件夹%HADOOP_HOME%\share\hadoop\hdfs
中。

英文:
The following error is a Bug in Hadoop 3.2.1.
This issue will be solved within the next release. For now, you can fix it temporarily using the following steps:
- Download
hadoop-hdfs-3.2.1.jar
file from the following link. - Rename the file name
hadoop-hdfs-3.2.1.jar
tohadoop-hdfs-3.2.1.bak
in folder%HADOOP_HOME%\share\hadoop\hdfs
- Copy the downloaded
hadoop-hdfs-3.2.1.jar
