Data Locality — Traditionally, to process the data, the data was fetched from the location it is stored, to the location where the application is submitted; however, in Hadoop, the processing application goes to the location of data to perform computation.

This reduces the delay in processing of data. Compatibility — Most of the emerging big data tools can be easily integrated with Hadoop like Spark. They use Hadoop as a storage platform and work as its processing system.

Standalone Mode — It is the default mode of configuration of Hadoop. It is useful for debugging and testing. All the daemons run on the same machine in this mode. It produces a fully functioning cluster on a single machine. Fully Distributed Mode — Hadoop runs on multiple nodes wherein there are separate nodes for master and slave daemons. The data is distributed among a cluster of machines providing a production environment. As a beginner, you might feel reluctant in performing cloud computing which requires subscriptions.

While you can install a virtual machine as well in your system, it requires allocation of a large amount of RAM for it to function smoothly else it would hang constantly.

Prerequisite : To install Hadoop, you should have Java version 1. Go this link —. Download the file according to your operating system. After downloading java version 1. Create a new user variable. Now we need to edit some files located in the hadoop directory of the etc folder where we installed hadoop.

The files that need to be edited have been highlighted. Edit the file core-site. Copy this xml property in the configuration in the file. Note: The path of namenode and datanode across value would be the path of the datanode and namenode folders you just created. Edit hadoop-env. To include those files, replace the bin folder in hadoop directory with the bin folder provided in this github link.

Download it as zip file. Extract it and copy the bin folder in it. If PATH environment exists in your system, you can also manually add the following two paths to it:. If you don’t have other user variables setup in the system, you can also directly add a Path environment variable that references others to make it short:.

Close PowerShell window and open a new one and type winutils. Edit file core-site. Edit file hdfs-site. Before editing, please correct two folders in your system: one for namenode directory and another for data directory.

For my system, I created the following two sub folders:. Replace configuration element with the following remember to replace the highlighted paths accordingly :. In Hadoop 3, the property names are slightly different from previous version. Refer to the following official documentation to learn more about the configuration properties:.

Hadoop 3. Edit file mapred -site. Replace configuration element with the following:. Edit file yarn -site. Refer to the following sub section About 3. Once this is fixed, the format command hdfs namenode -format will show something like the following:. Code fix for HDFS I’ve done the following to get this temporarily fixed before 3. I’ve uploaded the JAR file into the following location. Please download it from the following link:. And then rename the file name hadoop-hdfs Copy the downloaded hadoop-hdfs Refer to this article for more details about how to build a native Windows Hadoop: Compile and Build Hadoop 3.

You don’t need to keep the services running all the time. You can stop them by running the following commands one by one:. Log in with Microsoft account. Log in with Google account.

We will use Git Bash or 7 Zip to unzip Hadoop binary package. Apache Download Mirrors – Hadoop 3. And then choose one of the mirror link. The page lists the mirrors closest to you based on your location.

For me, I am choosing the following mirror link:. You can also directly download the package through your web browser and save it to the destination directory.

The command will take quite a few minutes as there are numerous files included and the latest version introduced many new features. After the unzip command is completed, a new folder hadoop Hadoop on Linux includes optional Native IO support. However Native IO is mandatory on Windows and without it you will not be able to get your installation working.

Thus we need to build and install it. Download all the files in the following location and save them to the bin folder under Hadoop folder. Remember to change it to your own path accordingly. After this, the bin folder looks like the following:.

Once you complete the installation, please run the following command in PowerShell or Git Bash to verify:. If you got error about ‘cannot find java command or executable’. Don’t worry we will resolve this in the following step. Now we’ve downloaded and unpacked all the artefacts we need to configure two important environment variables.
