Specifically, we need to set 3 environment variables for referencing Java, Spark & Hadoop. So let’s tell the windows where to find what we have installed. In my case, I have created the folder in the Windows directory: With the help of Hadoop, it can store the data as well.Īfter downloading of tgz file, extract the file and then create a folder named Spark and move the extracted file to the folder, For example, I have created a Spark folder in my Windows directory and pasted the contents there:įor running Hadoop on windows, we need an extra “.exe” file which enables Hadoop to have file access permissions, you can download this file from here, search for the Hadoop version that you have downloaded before and download relative winutils.exe, in my case I have downloaded the latest one for Hadoop 3.2.2.Īfter the download, you have to create a new folder, named Hadoop (or anything), inside the folder create another folder named bin, and leave the exe file there, so the structure will be "Haoop/bin/winutiles.exe". For small workloads, it is faster than Hadoop since it is using memory to process data but cannot save the data. Spark is an in-memory distributed computing engine and can run in a standalone mode without Hadoop, but this means you miss the data distribution feature. Hadoop is a distributed file system, Spark by itself doesn’t have a storage system, so if it is needed to be run in a multi-node mode, it is dependent on Hadoop or a similar package such as S3. Select the desired Spark and Hadoop version, else you can leave the default options and download the tgz file. The latest version at the writing time of this tutorial is 3.1.2, (Edit: I have seen the newer released version,3.2.0, which should not impact the steps of its installation anyway). The next step is to install Apache Spark, here, you can find the package of Spark prebuild with Apache Hadoop.
If you didn't install Java, you can download version 8 or 11 from one of the links below:Īfter downloading, execute and installing the package. In the above screenshot, my default Java version is 16, however, I have also installed Java 11 and set it as the environment variable (We will see this part in a moment).
You can check this by opening a command prompt or power shell and typing “java -version”.Ĭonsider Spark works with Java 8 /11. The first step is to check if you an installed Java on your windows.
