Offered by École Polytechnique Fédérale de Lausanne. Manipulating big data distributed over a cluster using functional concepts is rampant in industry, and is arguably one of the first widespread industrial uses of functional ideas. This is evidenced by the popularity of MapReduce and Hadoop, and most recently Apache Spark, a fast, in-memory distributed collections framework written in Scala. In this course, we'll see how the data parallel paradigm can be extended to the distributed case, using Spark throughout. We'll cover Spark's programming model in detail, being careful to understand how and when it differs from familiar programming models, like shared-memory parallel collections or sequential Scala collections. Through hands-on examples in Spark and Scala, we'll learn when important issues related to distribution like latency and network communication should be considered and how they can be addressed effectively for improved performance.  Learning Outcomes. By the end of this course you will be able to:…

Offered by Yandex. No doubt working with huge data volumes is hard, but to move a mountain, you have to deal with a lot of small stones. But why strain yourself? Using  Mapreduce and Spark you tackle the issue partially, thus leaving some space for high-level tools. Stop  struggling to make your big data workflow productive and efficient,  make use of the tools we are offering you.   This course will teach you how to: - Warehouse your data efficiently using Hive, Spark SQL and Spark DataFframes.  - Work with large graphs, such as social graphs or networks.  - Optimize your Spark applications for maximum performance.  Precisely, you will master your knowledge in: - Writing and executing Hive & Spark SQL queries; - Reasoning how the queries are translated into actual execution primitives (be it MapReduce jobs or Spark transformations); - Organizing your data in Hive to optimize disk space usage and execution times; - Constructing Spark DataFrames and using them to write ad-hoc analytical jobs easily; - Processing…
