The proliferation of Big Data processing environments such as Hadoop, Apache Spark, and HPCC Systems is driving the development of performance analysis tools in these distributed systems. The goal is to achieve high performance through the optimization of Big Data applications. However, tuning performance in a fine-grained manner is quite challenging due to the high complexity and massive size of the distributed systems. ECL-Watch is a data-flow based fine-grained comprehensive Big Data performance analysis tool utilizing the high level declarative dataflow programming language ECL in HPCC Systems. As a case study, we implement and optimize the Yinyang K-Means machine learning algorithm in ECL in HPCC Systems. The experimental results show that the performance of the native ECL version of the Yinyang K-Means algorithm increased significantly after tuning: from being about three times slower than the standard K-Means implementation in ECL, to become roughly 15% faster than standard K-Means.
