Cloud-based services are increasingly popular for big data analytics due to the flexibility, scalability, and cost-effectiveness of provisioning elastic resources on-demand. However, data analytics-as-a-service suffers from the overheads of data movement between compute and storage clusters, due to their decoupled architecture in existing cloud infrastructure. In this work, we propose a novel approach...
While MapReduce is inherently designed for batch and high throughput processing workloads, there is an increasing demand for non-batch processes on big data, e.g., interactive jobs, real-time queries, and stream computations. Emerging Apache Spark fills in this gap, which can run on an established Hadoop cluster and take advantages of existing HDFS. As a result, the deployment model of Spark-on-YARN...
