The project is managed by a group called the "Project Management Committee" (PMC). Spark is built on the concept of distributed datasets, which contain arbitrary Java or It applies a set of coarse-grained transformations over partitioned data and relies on the dataset lineage to recompute tasks in case of failures. Spark is a unified analytics engine for large-scale data processing. [6][7], Spark and its RDDs were developed in 2012 in response to limitations in the MapReduce cluster computing paradigm, which forces a particular linear dataflow structure on distributed programs: MapReduce programs read input data from disk, map a function across the data, reduce the results of the map, and store reduction results on disk. Inside Apache Spark the workflow is managed as a directed acyclic graph (DAG). # Given a dataset, predict each point's label, and show the results. A typical example of RDD-centric functional programming is the following Scala program that computes the frequencies of all words occurring in a set of text files and prints the most common ones. [33], In 2013, the project was donated to the Apache Software Foundation and switched its license to Apache 2.0.
