Foreseer: Workload-Aware Data Storage for MapReduce

Inter-job Write once read many (WORM) scenario is ubiquitous in MapReduce applications that are widely deployed on enterprise production systems. However, traditional MapReduce auto-tuning techniques can not address the inter-job WORM scenario. To address the shortcomings in existing works, this work presents a novel online cross-layer solution, FORESEER. It can automatically predict workloads' data access information and tune data placement parameters to optimize the over-all performance for an inter-job WORM scenario. In our experiments, we observe that FORESEER can achieve significant performance speedup (up to 37%) compared with previous work.
