In which deployment mode can we "Not" add nodes to a cluster in Apache Spark 2.3.1
When master is Local, your program will run on single machine that is your edge node.
To run it in distributed environment i.e. on cluster you need to select master as "Yarn".
When deployment mode is "client" (default) your edge node will become the master (where driver program will run).
When deployment mode is "cluster", any of the healthy node from the cluster becomes master
