It is a big challenge to pick up the best cloud configuration for recurring big data analytics jobs running in clouds. Prior efforts may get in a sub-optimal configuration due to a broad spectrum of cloud configurations with a few test runs, such as CherryPick. RP-CH, presented in this paper, is a resource provisioning system that leverages heuristic rules based on classification information to identify the optimal cloud configuration for big data analytics jobs, while the insight is classifying a job by comparing its resource preference and usage information with other jobs. Then, heuristic rules are used to distinguish bad samples from good ones in Bayesian optimization algorithm. The experiments on HiBench and SparkBench in Aliyun ECS show that the performance of job has been improved by 58% in average comparing with CherryPick, meanwhile the resource cost has been reduced by 44% in average.
