Reservation of nodes for spark job/ Labeling, Taint and Toleration of workers and spark pods
As an CP4d service provides we would like to use special worker nodes only for spark job execution called via the pyspark API. One reason for this is, that we sometimes see that the spark jobs use up all resources. In this scenario we would like at least that our WML batch jobs can run. The other reason is that we would like to use nodes with special hardware for spark execution.
