Try to set --total-executor-cores to limit how many total cores it can use.

instead of running 1 worker and giving it 8 cores, you can run 4 workers
with 2 cores each. Then, you get 4 executors with 2 cores each.

One indirect way to control the number of cores used in an executor is to
set spark.cores.max and set spark.deploy.spreadOut to be true. The
scheduler in the standalone cluster then assigns roughly the same number of
cores (spark.cores.max/number of worker nodes) to each executor for an
application
I have not found a way to control the cores yet. This effectively limits
the cluster to a single application at a time. A subsequent application
shows in the 'WAITING' State on the dashboard.

1. worker memory caps executor.
2. With default config, every job gets one executor per worker. This
executor runs with all cores available to the worker.

Hi,
What's the relationship between Spark worker and executor memory settings
in standalone mode? Do they work independently or does the worker cap
executor memory?
Also, is the number of concurrent executors per worker capped by the number
of CPU cores configured for the worker?
