Hi Vinayak,

Your properties file says:

spark.master=spark://127.0.0.1:7077

Do you have a spark standalone cluster running? Does the spark master reside on 127.0.0.1 and does it listen on 7077?

With spark on localhost, you can also simply take the "read-cql.properties¨ which uses all cores on localhost for running spark executors.

Best wishes,    Marc
