If one run pyspark without arguments on the gateway node on which CM is installed, one gets:

Any ideas why?
Is this warning OK: "WARN util.Utils: Service 'SparkUI' could not bind on port 4040. Attempting port 4041. "?

Forgot to say that
spark-submit --master=yarn --num-executors=3 lettercount.py
works fine.

Actually, I might have misinterpreted it: it works locally but not on the cluster

I think it worked before I configured the cluster to use TLS.

Same applies for spark-submit. It works locally but not on the cluster:
spark-submit --master=yarn --deploy-mode=client lettercount.py
works but
spark-submit --master=yarn --deploy-mode=cluster lettercount.py
crashes:
