Big Data Analytics in Java']Java with PCJ Library: Performance Comparison with Hadoop

The focus of this article is to present Big Data analytics using Java and PCJ library. The PCJ library is an award-winning library for development of parallel codes using PGAS programming paradigm. The PCJ can be used for easy implementation of the different algorithms, including ones used for Big Data processing. In this paper, we present performance results for standard benchmarks covering different types of applications from computational intensive, through traditional mapreduce up to communication intensive. The performance is compared to one achieved on the same hardware but using Hadoop. The PCJ implementation has been used with both local file system and HDFS. The code written with the PCJ can be developed much faster as it requires a smaller number of libraries used. Our results show that applications developed with the PCJ library are much faster compare to Hadoop implementation.
