Teach you how to be a master of spark big Data? Spark is now being used by more and more businesses, like Hadoop, where Spark is also submitting tasks to the cluster as a job, so how do you become a master of spark
Big data why Spark is chosenSpark is a memory-based, open-source cluster computing system designed for faster data analysis. Spark, a small team based at the University of California's AMP lab Matei, uses Scala to develop its core code with only 63 Scala files, very lightwei
Spark is a cluster computing platform originating from the University of California, Berkeley, amplab. It is based on memory computing and has hundreds of times better performance than hadoop. It starts from multi-iteration batch processing, it is a rare and versatile player that combines multiple computing paradigms, such as data warehouses, stream processing, and graph computing.

At present, real-time computing, analysis and visualization of big data is the key to the real application of big data in industry. To meet this need and trend, open source organization Apache proposes a framework based on the spark analysis and computation, with the advanta

This is distributed parallel computing, which is the essential point of big data.A partition is not a fixed 128M? No, because the last piece of data spans two blocks.A application ca
cause oom, this is a fatal problem, the first can not handle large-scale data, the second spark can not run on a large-scale distributed cluster! Later, the solution was to add the shuffle consolidate mechanism to reduce the number of files produced by shuffle to C*r (c represents the number of mapper that can be used at the cores side, and R represents the number of concurrent tasks in reducer). But at th
Spark's main programming language is Scala, which is chosen for its simplicity (Scala can be easily used interactively) and performance (static strongly typed language on the JVM). Spark supports Java programming, but for Java there is no such handy tool as Spark-shell, other than Scala programming, because the language on the JVM, Scala and Java can interoperate, the Java programming interface is actually

Three kinds of frameworks for streaming big data processing: Storm,spark and SamzaMany distributed computing systems can handle big data streams in real-time or near real-time. This article provides a brief introduction to the three Apache frameworks, such as Storm,

Many data scientists prefer to use the R language, and it is gratifying that the integration of Spark and R-Sparkr has become the spark's emerging capabilities. Apache Zeppelin (https://zeppelin.incubator.apache.org/) is an emerging tool that provides Spa
When it comes to big data, I believe you are not unfamiliar with the two names of Hadoop and Apache Spark. But we tend to understand that they are simply reserved for the literal, and do not think deeply about them, the following may be a piece of me to see what the similarities and differences between them.The problem-solving dimension is different.First, Hadoop
