PERFORMANCE-EFFICIENT RECOMMENDATION AND PREDICTION SERVICE FOR BIG DATA FRAMEWORKS FOCUSING ON DATA COMPRESSION AND IN-MEMORY DATA STORAGE INDICATORS.

The MapReduce framework manages Big Data sets by splitting the large datasets into a set of distributed blocks and processes them in parallel. Data compression and in-memory file systems are widely used methods in Big Data processing to reduce resource-intensive I/O operations and improve I/O rate correspondingly. The article presents a performance-efficient modular and configurable decision-making robust service relying on data compression and in-memory data storage indicators. The service consists of Recommendation and Prediction modules, predicts the execution time of a given job based on metrics, and recommends the best configuration parameters to improve Hadoop and Spark frameworks' performance. Several CPU and dataintensive applications and micro-benchmarks have been evaluated to improve the performance, including Log Analyzer, WordCount, and K-Means. [ABSTRACT FROM AUTHOR]
