Issue installing Java 8 in dockerfile

[clemEssien]

Problem description

 Java 8 is not installed when the command to install is supplied in the Dockerfile. Java 8 is a requirement for the Spark 
 Session to be initialized and the JAVA_HOME environment variable should be set
 Unable to locate package openjdk-8-jdk

''' ERROR [ 3/17] RUN apt-get install openjdk-8-jdk 1.1s

---

[ 3/17] RUN apt-get install openjdk-8-jdk:

6 0.301 + apt-get install openjdk-8-jdk

6 0.996 Reading state information...

6 1.086 E: Unable to locate package openjdk-8-jdk

'''

Steps to reproduce the issue

Add the following lines into the Dockerfile

1. RUN apt-get update
2. RUN apt-get install openjdk-8-jdk
3. Then run docker-compose up

Expected behavior

     Java 8 is expected to be installed while creating the docker image

Attempted fixes

    I tried to install from official repositories instead of the manual installation by running the following commands:

• apt-get install oracle-java8-installer
• add-apt-repository ppa:webupd8team/java

@clemEssien Try installing the system library default-jre, see example.

[clemEssien]

The default-jre installs Java 11. The installation specifies Java 8. However, I tried it a few times, the latest error here is a Java gateway exception i.e. ''' Exception in thread "main" java.io.FileNotFoundException:
