Spark sets executor CPU requests equal to limits, so a Kubernetes cluster reserves twice the CPU it uses and refuses to schedule pending pods. Kubernetes has no native overcommit. Here is the mutating-webhook operator I use to fix it.
Introduction Benchmarking remains a critical (and often underestimated) tool when designing or validating large-scale data platforms.

TPCx-HS is one of those benchmarks: designed to Read more
