Dynamic Allocation Property set to true by default is false also dynamic initial and max executors should be set:
Executor and Driver memory need to be set:
Example of spark-submit
spark-submit --master yarn-cluster \
--driver-cores 2 \
--driver-memory 2G \
--num-executors 10 \
--executor-cores 5 \
--executor-memory 2G \
