Hi, I am launching through code (client mode) a Spark program to run in Hadoop. Whenever I check the executors tab of Spark UI I always get 0 as the number of vcores for the driver. I tried to change that using *spark.driver.cores*, or also *spark.yarn.am.cores* in the SparkSession configuration but in vain. I also tried to set those parameters in spark-defaults but, again, with no success. To note that in the environment tab, the right config is displayed.
Could this be the reason for a *CollectAsList *to freeze the execution (not having enough CPU)?
