I have Ubuntu Desktop 18.04 LTS installed in VMWare. Now I have Apache Hadoop and Apache Spark installed in it. A pop up menu has come up offering me to upgrade to Ubuntu Desktop 20.04 LTS. I am willing to upgrade. However, I am worried that if I upgrade to version 20.04, I may lose the Hadoop and Spark settings.
So this is my question: If I upgrade to Ubuntu 20.x from my present version which already has Hadoop and Spark configured/installed in it, will I lose these settings, and will I have to re-install/re-configure once I upgrade to the new Ubuntu 20.04?
