Install Prerequisites
.NET for Apache Spark runs on the 64-bit version of the Windows operating system and assumes the same from this point onwards.
Install 7-zip
Apache Spark is downloaded as a compressed .tgz file. You'll need 7-zip to extract the file.
If you already have an alternative extraction program installed, you can use that instead.
Once you've installed everything and set your environment variables, open a new command prompt or terminal and run the following command:
Command prompt
spark-submit --version
If the command runs and prints version information, you can move to the next step.
If you receive a 'spark-submit' is not recognized as an internal or external command error, make sure you opened a new command prompt.
Extract Apache Spark
In your terminal, move to the folder that contains the file you just downloaded then run the following command:
In your command prompt, run the following command to create your app:
In your terminal, run the following command to create your app:
Command prompt
dotnet new console -f netcoreapp3.1 -o mySparkApp
Then, navigate to the new directory created by the previous command:
Command prompt
cd mySparkApp
The dotnet command creates a new application of type console for you. The -o parameter creates a directory named mySparkApp where your app is stored, and populates it with the required files. The cd mySparkApp command puts you into the newly created app directory.
Install the NuGet package
