Install hadoop on windows(non-virtual machine, such cygwin)

Download
Before starting make sure you have this two softwares

• Hadoop 2.7.1
• Java – Jdk 1.7+

Extract downloaded tar file

Configuration
Step 1 – Windows path configuration
set HADOOP_HOME path in enviornment variable for windows
Right click on my computer > properties > advanced system settings > advance tab > environment variables > click on new

Set hadoop bin directory path
Find path variable in system variable > click on edit > at the end insert ‘; (semicolon)’ and paste path upto hadoop bin directory in my case it’s a

F:/Hortanwork/1gbhadoopram/Software/hadoop-2.7/hadoop-2.7.1/bin

Step 2 – Hadoop configuration
Edit hadoop-2.7.1/etc/hadoop/core-site.xml, paste the following lines and save it.

<configuration>
<property>
       <name>fs.defaultFS</name>
       <value>hdfs://localhost:9000</value>
   </property>
</configuration>

Edit hadoop-2.7.1/etc/hadoop/mapred-site.xml, paste the following lines and save it.

<configuration>
   <property>
       <name>mapreduce.framework.name</name>
       <value>yarn</value>
   </property>
</configuration>

Edit hadoop-2.7.1/etc/hadoop/hdfs-site.xml, paste the following lines and save it, please create data folder somewhere and in my case i have created it in myHADOOP_HOME directory

<configuration>
<property>
       <name>dfs.replication</name>
       <value>1</value>
   </property>
   <property>
       <name>dfs.namenode.name.dir</name>
       <value>/f:/Hortanwork/1gbhadoopram/Software/hadoop-2.7/hadoop-2.7.1/data/namenode</value>
   </property>
   <property>
       <name>dfs.datanode.data.dir</name>
     <value>/f:/Hortanwork/1gbhadoopram/Software/hadoop-2.7/hadoop-2.7.1/data/datanode</value>
   </property>
</configuration>
OR

Edit hadoop-2.7.1/etc/hadoop/yarn-site.xml, paste the following lines and save it.

<configuration>
   <property>
       <name>yarn.nodemanager.aux-services</name>
       <value>mapreduce_shuffle</value>
   </property>
   <property>
       <name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name>
       <value>org.apache.hadoop.mapred.ShuffleHandler</value>
   </property>
</configuration>

Edit hadoop-2.7.1/etc/hadoop/hadoop-env.cmd, comment existing%JAVA_HOME% using @rem at start, give proper path and save it. (my jdk is in program files to avoid spaces i gave PROGRA~1)

Demo

Step 3 – Start everything

Very Important step!!!!

3.1） Before starting everything you need to add some [dot].dll and [dot].exe files of windows please download bin folder from my github repository –sardetushar_gitrepo_download

or download from   https://github.com/steveloughran/winutils/tree/master/hadoop-2.7.1/bin

3.2） copy all the files dowloaded into the %HADOOP_HOME%\bin folder (The download file contains .dll and .exe file (winutils.exe for hadoop 2.7.1) which adapte for windows os).

3.3) Open cmd and type ‘hdfs namenode -format’ – after execution you will see below logs

3.4) Open cmd and point to sbin directory and type ‘start-all.cmd’

C:\UserDefined\BigData\hadoop-2.7.1\sbin>start-all.cmd

It will start following process

Namenode

Datanode

YARN resourcemanager

YARN nodemanager

JPS – to see services are running
open cmd and type – jps (for jps make sure your java path is set properly)

GUI
Step 4 – namenode GUI, resourcemanager GUI
Resourcemanager GUI address – http://localhost:8088

Namenode GUI address – http://localhost:50070
