I have an EMR Cluster that has correctly spawned 6 executors, 4 cores each. When the spark job is run on the cluster, it creates 6 Containers, which are each only assigned 1 core, How do i specify the number of cores each Container is allocated?
Relevant config:
spark.executor.instances: 5
spark.executor.cores: 4
yarn.scheduler.minimum.allocation.vcores: 4
