The Hidden Cost of Container Networking: CNI Overlay Throughput Constraints in Kubernetes-Managed Apache Spark Versus Native Hadoop MapReduce on Bare-Metal Edge Hardware
Although cloud-native Spark offers a clear performance advantage over traditional MapReduce for speed-sensitive tasks, achieving high throughput requires high-bandwidth memory provisioning and the deployment of kernel-level eBPF networking techniques to mitigate Kubernetes network overhead.
