Hadoop 2.7.2 single node installation windows 10

I am new to hadoop and I have given my best shot to try to setup hadoop single node installation on my windows machine on my own but obviously I failed and now need some help.

I followed the tutorial from wiki.apache.org and did everything as stated except the steps involving building (2.3 - 2.7) since I downloaded the binary distribution in the first place.

The problem is that after having all my files modified as the tutorial states, when I try to run the following command given at step 3.4:

%HADOOP_PREFIX%\bin\hdfs namenode -format

It says:

+================================================================+
|      Error: HADOOP_HOME is not set correctly                   |
+----------------------------------------------------------------+
| Please set your HADOOP_HOME variable to the absolute path of   |
| the directory that contains the hadoop distribution            |
+================================================================+
'-Dhadoop.security.logger' is not recognized as an internal or external command,
operable program or batch file.

I have already adding HADOOP_HOME to my enviroment variables as stated here but it didn't work out. I tried to google Dhadoop.security.logger but could not find anything of much use.

Right now my hadoop-env.cmd file looks like this

Please take a look and help me with the possible fix.

I have the same issue, all config files were set correctly, all environment variables were set correctly.

My issue: I had used winZip to unzip the hadoop-2.8.0.tar.gz file and it had some issues with directory depth when unzipping. I figured I'd move on and come back to that if it was an issue. After messing around with environment variables for an hour or so, I unzipped the gz file with winRAR instead (which doesn't have directory depth issues) and then hadoop version and hdfs namenode -format starting working fine... So check to see if that's your issue as well. Basically some of the share directory probably won't be there if you used winZIP and that needs to be part of the classpath.

So Hadoop 2.7.2 seems to have a problem. The 2.7.1 version just worked fine for me.
