Absrtact: Spark is a new generation of large data distributed processing framework after Hadoop, which is led by the Matei Zaharia of UC Berkeley. I can only say that it is a god-like character created by the artifact, details please bash HTTP://WWW.SPARK-PROJECT.ORG/1 Scala installation Currently, the latest version of Spark is 0.5, because when I write this document, the version is still 0.4, so all the d

1. Spark is an open-source cluster computing system based on memory computing, which is designed to make data analysis faster. So the machine running spark should be as large as possible in memory, such as 96G or more.2. All operation of Spark is based on RDD, the operation is divided into 2 major categories: transformation and action.3.

What is SparkSpark is an open-source cluster computing system based on memory computing that is designed to make data analysis faster. Spark is very small, developed by Matei, a team based in the AMP Lab at the University of California, Berkeley. The language used is Scala, the core part of the project's code is only 63 scala files, very short and concise. Spark is an open-source cluster computing environme
