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

Of course, you can also use MVN packaging to perform mvn clean package Pom-related configuration in terminal: question two, SBT packaging Using the SBT package will only package the program, and the dependent jar packages will not be included in the same jar, and the sbt-assembly plug-in

Compilation of Spark Source code package There are only two types of Spark Source code package: Maven and SBT (Simple Build Tool), which are only applicable to different scenarios: Maven Compilation SBT Compilation IntelliJ IDEA compilation (can be compiled using Maven or SBT plug-in), suitable for developers Package deployment generation (embedded Maven compilat

Welcome to Exchange Study: email:sparkexpert@sina.com There's a lot of installation on Spark R on the web, but it always goes wrong in that process. Of course the most common problem is: launching SBT from Sbt/sbt-launch-0.13.6.jar error:invalid or corrupt jarfile Sbt/sbt-la

The previous article was a primer on spark SQL and introduced some basics and APIs, but it seemed a step away from our daily use.There are 2 uses for ending shark:1. There are many limitations to the integration of Spark programs2. The Hive Optimizer is not designed for spark, and the computational model is different, making the Hive optimizer to optimize the spark program to encounter bottlenecks.Here's a look at the infrastructure of Spark SQL:Spark1.1 will support the spark SQL CLI when it is

1. The concept of the channel A channel represents a stream of data to a device (disk or tape) and produces a corresponding server session on the target database or a secondary database instance (server sessions) Multiple channels generate multiple server sessions, which will complete backup, restore, and recovery operations, and so on Channels are divided into disk channels for backup or restore to disk (disk channel), Backup to tape channel (SBT)
