In-memory distributed processing for large datasets… How to connect to SQL Server using Apache Spark? The Spark documentation covers the basics of the API and Dataframes, there is a lack of info. and examples on actually how to get this feature to work.
First, what is Apache Spark? Apache Spark is an open source big data processing framework built around speed, ease of use, and sophisticated analytics. A fast and general processing engine compatible with Hadoop data. It can run in Hadoop clusters through YARN or Spark’s standalone mode, and it can process data in HDFS, HBase, Cassandra, Hive, and any Hadoop InputFormat. It is designed to perform both batch processing (similar to MapReduce) and new workloads like streaming, interactive queries, and machine learning.
