The Hidden Cost of Container Networking: CNI Overlay Throughput Constraints in Kubernetes-Managed Apache Spark Versus Native Hadoop MapReduce on Bare-Metal Edge Hardware
This paper examines the impact of migrating large-scale data processing frameworks from bare-metal servers to cloud-native environments on system performance. Specifically, we compare traditional Hadoop MapReduce deployed on bare-metal infrastructure with Apache Spark running on Kubernetes, using a 200 GB TeraSort work...
