Scala-IDE : http://scala-ide.org/download/sdk.html (requires JDK 8) (Basically eclipse)
https://spark.apache.org/downloads.html (Get v.2.3.0 pre-build for Hadoop 2.7 and later)
Both these are just zip files. ...all that needs to be done is download and unzip them and keep it in a folder in the home directory (for all machines) (works on Windows, Linux and Mac), Nothing else is required. No installation is required in both cases.
