Only one job will run in parallel in Spark with four cores and four worker nodes.
In Spark, each core can only run one task at a time, so with four cores, only four tasks can run concurrently.
Since there are four worker nodes, each with four cores, a total of four tasks can run in parallel.
Therefore, only one job will run in parallel in this scenario.
