How to use multiple spark version?

Question

I want to install Spark 1 and 2 without uninstalling either and use them depending on my need. How can I do this?

Answer 1

You can use the  SPARK_MAJOR_VERSION for this. Suppose you want to use version 2, set this:

export SPARK_MAJOR_VERSION=2 

Then to run, use:

spark-submit --version
