This course focuses onSpark, the hottest, most popular and promising technology in the big Data world today. In this course, from shallow to deep, based on a large number of case studies, in-depth analysis and explanation of Spark, and will contain completely from the enterprise real complex business needs to extract the actual case. The course will cover Scala programming, spark core programming,

It claims that, when used in memory, it is up to 100 times times faster than MapReduce, and when used on disk, it is up to 10 times times faster than MapReduce. It can be used with Hadoop and Apache Mesos, or it can be used standalone.Supported operati

Big Data We all know about Hadoop, but there's a whole range of technologies coming into our sights: Spark,storm,impala, let's just not come back. To be able to better architect big data projects, here to organize, for technicians, project managers, architects to choose the right technology, understand the relationship between the various technologies of big data, choose the right language. We can read this

?? At present, there is only one machine, the first to practice the hand (no software installed on the server) try Spark's stand-alone deployment.?? Several parameters:?? jdk-1.7+?? Hadoop-2.6.0 (pseudo-distributed);?? Scala-2.10.5;?? Spark-1.4.0;?? Here are the specific configuration procedures Install jdk 1.7+ Download URL http://www.oracle.com/technetwo

Preface I recently contacted Spark and wanted to experiment with a small-scale spark distributed cluster in the lab. Although only with a single stand-alone version (standalone) of the pseudo-distributed cluster can also do experiments, but the sense of little meaning, but also in order to realistically restore the real production environment, after looking at some information, know that

First, pseudo-distribution installation Spark installation environment: Ubuntu 14.04 LTS 64-bit +hadoop2.7.2+spark2.0.0+jdk1.7.0_76 Linux third-party software should be installed in the/OPT directory, the Convention is better than the configuration, Following this principle is a good environment to configure the habit. So the software installed here is in the/OPT directory. 1, install jdk1.7 (1) Download jd
