Machine Learning in Java - Second Edition

Apache Spark

Apache Spark, or simply Spark, is a platform for large-scale data processing builds atop Hadoop, but, in contrast to Mahout, it is not tied to the MapReduce paradigm. Instead, it uses in-memory caches to extract a working set of data, process it, and repeat the query. This is reported to be up to ten times as fast as a Mahout implementation that works directly with data stored in the disk. It can be grabbed from https://spark.apache.org.

There are many modules built atop Spark, for instance, GraphX for graph processing, Spark Streaming for processing real-time data streams, and MLlib for machine learning library featuring classification, regression, collaborative filtering, clustering, dimensionality reduction, and optimization. ...
