Second, there are powerful for expressions, partial functions, implicit conversions, and so on, the following mainly introduces Scala concurrent (parallel) programming.ii. introduction of SBTWith the Scala language programming, it's best to use the SBT framework, which automati

Recently want to test the performance of Kafka, toss a lot of genius to Kafka installed to the window. The entire process of installation is provided below, which is absolutely usable and complete, while providing complete Kafka Java client code to communicate with Kafka. Here you have to spit, most of the online articles about how to install Kafka on Windows are either incomplete or Kafka client code is wrong or not based on the 0.8 version. But it must be recalled that this article simply intr

Because we are currently working on a quad-rotor project. So I searched for some information on the Internet and transferred the following article about the four-rotor entry-level knowledge. 1. StructureThe rotor is symmetric distributed in the four directions of the front and back of the body, left and right. The four rotor is in the same height plane, and the structure and radius of the four rotor are the same. The four motors are installed in the b

The premise of this article is that scala, sbt, and spark have been correctly installed. Briefly describe the steps to mount the program to the cluster for running: 1. Build the sbt standard project structure: Where :~ /Build. the sbt file is used to configure the basic information of the project (project name, organization name, project version, scala version us

Qingming Holiday toss for two days, summed up two ways to use the IDE for the Spark program, record: The first method is simpler, both of which are compiled with SBT. Note: There is no need to install the Scala program locally, otherwise there is a version compatibility issue when compiling the program. First, based on the NON-SBT way Create a Scala idea project We use the NON-

by each task, therefore, some variables are not shared. However, I need to share the variables that can be shared in the task or between the task and the dynamic program. Spark supports two types of shared variables: Broadcast variable: Can be stored in all the points, used to store variables (only) Accumulators: Only variables used for addition, such as sum Some examples of Nantong show some features. It is better to be familiar with Scala, especially the packet method. Note that Spark can run
