1, under the Java Spark Development environment Construction 1.1. JDK Installation Install the JDK under Oracle, I installed JDK 1.7, install the new system environment variable java_home, the variable value is "C:\ProgramFiles\Java\jdk1.7.0_79", depending on the installation of the road. Add C:\Program Files\java\jdk1.7.0_79\bin and C:\ProgramFiles\Java\jre7\bin at the same time under the system variable path. 1.2

Since Spark is written in Scala, Spark is definitely the original support for Scala, so here is a Scala-based introduction to the spark environment, consisting of four steps: JDK installation, Scala installation, spark installation, Download and configuration of Hadoop. In order to highlight the "from Scratch" characte

The installation of Spark is divided into several modes, one of which is the local run mode, which needs to be decompressed on a single node without relying on the Hadoop environment. Run Spark-shell Local mode running Spark-shell is very simple, just run the following command, assuming the current directory is $spark_home $ master=local $ bin/

As an open-source data processing framework, spark caches intermediate data directly into memory during data calculation, which can greatly improve processing speed, especially for complex iterative computations. Spark mainly includes Sparksql,sparkstreaming,spark mllib and figure calculations.Introduction to spark Cor

Brief introductionIn general, each spark application consists of a driver that runs the user's main function and performs a variety of parallel operations on a cluster. The main abstraction (concept) provided by Spark is an elastic distributed dataset, which is a collection of elements that can be manipulated in parallel by dividing it into different nodes of the cluster . The creation of Rdds can start wit
