(1)准备工作 1) 安装JDK 6或者JDK 7 2) 安装scala 2.10.x (注意版本) 2)下载Intellij IDEA最新版(本文以IntelliJ IDEA Community Edition 13.1.1为例说明,不同版本,界面布局可能不同) 3)将下载的Intellij IDEA解压后,安装scala插件,...

分布式是一个概念,一个理论。任何需要大数据处理的领域都可以应用分布式,而Hadoop、spark等是分布式计算框架,只要需要应用到分布式处理的系统,都可以使用它们。现在互联网上这么多信息,安全领域也早就进入了大数据阶段了,身份认证,授权,...

Spark与Hadoop一样,是一种开源的集群计算环境,但在特定工作负载情况下比Hadoop更高效。Spark采用基于内存的分布式数据集,优化了迭代式的工作负载以及交互式查询。Spark采用Scala语言实现,使用Scala作为应用框架。与Hadoop不同的是,Spark和S...
