how export addresses into PATH for running pyspark in Amazon EC2

Question

Hi I have installed Spark and Python and Jupyter Notebook in Amazon AWS EC2 but when I run "jupyter notebook" in the command prompt it just provides an address for "jupyter notebook" when I open the jupyter notebook, I can't run pyspark commands. I just can run python commands. I googled it and found these commands:

export SPARK_HOME=/home/ubuntu/spark-3.0.1-bin-hadoop3.2

export PATH=$SPARK_HOME/bin:$PATH

export PYTHONPATH=$SPARK_HOME/python:$PYTHONPATH

After executing them, when I typed "jupyter notebook" I access a "jupyter notebook" that can support pyspark. However, when I close my commands prompt and logged in later, I have to type the above commands again to be able to have "pyspark" in the "jupyter notebook". My question: how permanently save those variables in "PATH" of environment variable. And how can see all of the environment variables including the ones that I entered through above commands.

Answer 1

It's can be a similar case for environment variables and your local terminal. To have some extra variables exported, you need to save those export commands in your EC2 machine .bashrc file
