SPARK Job Performance Analysis and Prediction Tool

Spark is one of most widely deployed in-memory big data technology for parallel data processing across cluster of machines. The availability of these big data platforms on commodity machines has raised the challenge of assuring performance of applications with increase in data size. We have build a tool to assist application developer and tester to estimate an application execution time for larger data size before deployment. Conversely, the tool may also be used to estimate the competent cluster size for desired application performance in production environment. The tool can be used for detailed profiling of Spark job, post execution, to understand performance bottleneck. This tool incorporates different configurations of Spark cluster to estimate application performance. Therefore, it can also be used with optimization techniques to get tuned value of Spark parameters for an optimal performance. The tool's key innovations are support for different configurations of Spark platform for performance prediction and simulator to estimate Spark stage execution time which includes task execution variability due to HDFS, data skew and cluster nodes heterogeneity. The tool using model [3] has been shown to predict within 20% error bound for Wordcount, Terasort,Kmeans and few SQL workloads.
