Suhass, When I referred to interactive shells, I was referring the the Scala & Python interactive language shells. Both Python & Scala come with respective interacive shells. By just typing “python” or “scala” (assume the installation bin directory is in your $PATH), it will put fire up the shell.
As for the “pyspark” and “spark-shell”, they both come with the Spark installation and are in $spark_install_dir/bin directory. Have a go at them. Best way to learn the language.
