Well. When you or application log in to Linux host (whether a physical tin box or a virtual node), they execute a script called .bashrc at home directory.
If it is a scheduled job then it will also execute the same as well. In my Google Data proc cluster of three (one master and two workers), in the master node I automatically activate the virtual environment as below cd /usr/src/Python-3.7.9/environments; source virtualenv/bin/activate Then I execute spark-submit script as follows: spark-submit \ --master yarn \ --deploy-mode client \ --jars /home/hduser/jars/spark-bigquery-latest.jar \ analyze_house_prices_GCP.py Note that as I understand using virtual environment is only necessary in the master node, I don't touch worker nodes. My suggestion is that you first test running a script in your master node interactively once you have activated your virtual environment and see how it goes.
