About Apache Spark

Apache Spark is an open source analytics engine for big data. It can run batch and streaming workloads, and has modules for machine learning and graph processing. Developers can write interactive code from the Scala, Python, R, and SQL shells. Spark runs almost anywhere — on Hadoop, Apache Mesos, Kubernetes, stand-alone, or in the cloud. It can access data in HDFS, Apache Cassandra, Apache HBase, Apache Hive, and hundreds of other data sources.
