Install spark

hi everybody

I’m trying to install Spark on my computer to connect it with Knime

(I applied the steps from YouTube)

However, I encounter a problem when I try to verify the installation using cmd. The result is that it cannot be recognized.

Does anyone know the correct steps to install Spark and how can I connect it to Knime?

Thanks to all. Any useful information will help me

link to youtube or any things will help
