arrow_back Install Hadoop 3.0.0 on Windows (Single Node)
Very well written guide. Thanks for posting this. Hadoop on Windows can be a daunting task. I have had several issues while I install Hadoop 2.9 on my machine. It encouraged me to document the working steps and ended up writing this Blog Post.

Thanks anyway for writing this. It helps a lot of learners out there.
Is JAVA_HOME environment variable configured correctly in your system? The value should point to your JDK location.

The system cannot find the path specified.
Error: JAVA_HOME is incorrectly set.
Please update C:xxx\hadoop-2.9.1\etc\hadoop\hadoop-env.cmd
DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.

Hi. thank you for your answer. I found a solution for my problem. If it can help someone, the problem was related to the syntax of my system username. It contains a space. So, to fixe it, you can edit /etc/hadoop/hadoop-env.cmd, at the end of this file, you will find set HADOOP_IDENT_STRING=%USERNAME% , change this with a string that you want but without space. For example: set HADOOP_IDENT_STRING=myuser, the problem will be fixed.
Did you follow all the steps in this post? For example, you need to ensure winutils tool is installed:
Overwrite your bin folder (%HADOOP_HOME%\bin) with the files from this link:
https://github.com/steveloughran/winutils/tree/master/hadoop-3.0.0/bin
The current available version is 3.0.0 and I am not very sure whether it can fix the issue for 3.0.1 but worth giving it a try.

Hi,
I tried your guidelines for installing Hadoop 3.2.0 on my Windows 10 but unfortunately I am unable to start it. I am stuck at the point where you stated the command hadoop namenode -format . I am getting this message at the end of the command Shutting down NameNode at {Username}/192.168.0.200.
But no descriptive error other than that. Can you help me please?
