# Install Hadoop in Windows 7
A guide to walk through the Hadoop installation process on windows 7 (for Windows 10 see [How to install Hadoop in 5 Steps in Windows 10](https://medium.com/analytics-vidhya/hadoop-how-to-install-in-5-steps-in-windows-10-61b0e67342f8)).
This tutorial will show how to install Hadoop on Windows 7, breaking down the installation into clear steps.

## I- Download Files
* Download Hadoop [hadoop-2.9.2.tar.gz](https://archive.apache.org/dist/hadoop/core/hadoop-2.9.2/)
* Download [java 11](https://www.oracle.com/java/technologies/javase/jdk11-archive-downloads.html)
* Download [winutils](https://github.com/cdarlint/winutils/tree/master), we will need the bin files that are in [hadoop-2.9.2/bin](https://github.com/cdarlint/winutils/tree/master/hadoop-2.9.2/bin)
## II- Setup Folders and Files
1. **Create new folder in `C:\` named `hadoop`**
We will extract `hadoop-2.9.2.tar.gz` to this folder `C:\hadoop\`.
2. **Created 3 folders**
- First folder named `data`, should be created in `C:\hadoop\hadoop-2.9.2\`. Like `C:\hadoop\hadoop-2.9.2\data`.
- Second folder named `datanode`, should be created in `C:\hadoop\hadoop-2.9.2\data\`. Like `C:\hadoop\hadoop-2.9.2\data\datanode`.
- Third folder named `namenode`, should be created also in `C:\hadoop\hadoop-2.9.2\data\`. Like `C:\hadoop\hadoop-2.9.2\data\namenode`.
3. **Extract the `winutils-master.zip` file**
Enter to `winutils-master` :
We will using Hadoop 2.9.2 :
so we will copy all files that are in the bin folder of hadoop-2.9.2 folder `winutils-master\hadoop-2.9.2\bin\` :
to `C:\hadoop\hadoop-2.9.2\bin`. Replacing all files :
4. **Setup Java 11**
To avoid errors, create a folder in `C:\` named `java`, then extract the `jdk-11.0.19_windows-x64_bin.zip` file to `C:\java`, (like we did in step II-1-) :
Here is the output of the extreaction :
## III- Setup Environment Variables
click on `windows key` then search for `environment variables`, then click on `edit environment variables for your account`
1. **JAVA_HOME :**
If you don't have a `JAVA_HOME` variable, click on `new` to add it :
- Then in the `variable name` type :
```plaintext
JAVA_HOME
```
- And in the `variable value` type :
```plaintext
C:\java\jdk-11.0.19
```
2. **HADOOP_HOME :**
- Click on `new` to add `HADOOP_HOME` variable, then in the `variable name` type :
```plaintext
HADOOP_HOME
```
- And in the `variable value` type :
```plaintext
C:\hadoop\hadoop-2.9.2
```
3. **Path :**
Scroll to `Path` and select it, then click on `Edit`, and add this to the begining of `variable value` type :
```plaintext
%JAVA_HOME%\bin;%HADOOP_HOME%\bin;%HADOOP_HOME%\sbin;
```
4. **Verifying :**
* Verifying `Java` :
Open cmd and type :
```batch
java -version
```
The output should be like :
```plaintext
java version "11.0.19" 2023-04-18 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.19+9-LTS-224)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.19+9-LTS-224, mixed mode)
```
* Verifying `JAVA_HOME` :
In cmd type :
```batch
echo %JAVA_HOME%
```
The output should be like :
```plaintext
C:\java\jdk-11.0.19
```
* Verifying `HADOOP_HOME` :
In cmd type :
```batch
echo %HADOOP_HOME%
```
The output should be like :
```plaintext
C:\hadoop\hadoop-2.9.2
```
* Verifying `PATH` :
In cmd type :
```batch
echo %PATH%
```
The output should be like :
```plaintext
C:\java\jdk-11.0.19\bin;C:\hadoop\hadoop-2.9.2\bin;C:\hadoop\hadoop-2.9.2\sbin;C:\Use...
```
## IV- Setup Configuration Files
Go to `C:\hadoop\hadoop-2.9.2\etc\hadoop` to find the file that we will edit.
1. **Modifying the `core-site.xml` file :**
```plaintext
hadoop.tmp.dir
C:\hadoop\hadoop-2.9.2\tmp
fs.default.name
hdfs://localhost:9000
```
2. **Modifying the `hdfs-site.xml` file :**
```plaintext
dfs.replication
1
dfs.namenode.name.dir
C:\hadoop\hadoop-2.9.2\data\namenode
dfs.datanode.data.dir
C:\hadoop\hadoop-2.9.2\data\datanode
```
3. **Modifying the `mapred-site.xml` file :**
```plaintext
mapreduce.framework.name
yarn
```
4. **Modifying the `yarn-site.xml` file :**
```plaintext
yarn.nodemanager.aux-services
mapreduce_shuffle
yarn.nodemanager.aux-services.mapreduce.shuffle.class
org.apache.hadoop.mapred.ShuffleHandler
```
5. **Verifying the `hadoop-env.cmd` file :**
- Make sure that JAVA_HOME is set correctly :
```plaintext
set JAVA_HOME=%JAVA_HOME%
```
## V- Testing
1. **Verifying hadoop :**
Use this command in the cmd :
```batch
hadoop version
```
2. **Formatting Namenode :**
Only for the first time to start hadoop use :
```batch
hdfs namenode -format
```
3. **Start hadoop :**
First run :
```batch
start-dfs
```
and two windows will popup :
Then run :
```batch
start-yarn
```
and two windows will popup :
4. **jps :**
To verify that all works, run :
```batch
jps
```
The output is like :
```plaintext
6896 NodeManager
6388 ResourceManager
8488 DataNode
2028 NameNode
9788 Jps
```
5. **Verify namenode :**
In a browser, open this link :
```plaintext
localhost:50070
```
6. **Verify Resourcemanger :**
In a browser, open this link :
```plaintext
http://localhost:8088
```
## VI- Some Hadoop Commands
1. **Create a folder in hdoop hdfs:**
let's start with creating a folder :
```batch
hadoop fs -mkdir /aissam_data
```
and show it :
```batch
hadoop fs -ls /
```
To see it in the browser, open this link :
```plaintext
localhost:50070
```
When we click on `aissam_data` we see that it is empty :
2. **copy data example to it :**
I have a file in my computer names `myData.txt`, that have this text inside it:
```plaintext
windows data Big
windows 7 installation BigData
10 guid Big Data
TESTY TEST
Windows
```
So, let't cpoy it to hadoop:
```batch
hdfs dfs -put C:\hadoop\myData.txt /aissam_data/data_.txt
```
To list it :
```batch
hdfs dfs -ls /
```
```batch
hdfs dfs -ls /aissam_data
```
To see its size :
```batch
hadoop fs -du /aissam_data/data_.txt
```
To see its contenue :
```batch
hadoop fs -cat /aissam_data/data_.txt
```
* for more command, see /2_hadoop_commands\hadoop_commands.txt
## VII- Stop Hadoop
To stop run :
```batch
stop-dfs
```
Then run :
```batch
stop-yarn
```
