Hi, I have the spark 2.3.3 version. I am using below configuration
driver memory : 16 GB
Excecuors memory : 12 GB
code per exceutor : 5 cores.
I have spark streaming job which receives certain requests and based on the request we read data from Cassandra and process the request. I noticed that some time CPU usages 659 for my running spark streaming process on driver node. Similar behaviour is noticed on workers nodes also. Can someone help me what could be the root cause .
