The main content of this section:I. Data acceptance architecture and design patternsSecond, the acceptance of the data source interpretationSpark streaming continuously receives data, with receiver's spark application in mind.Receiver and driver in different processes, receiver to receive data after the continuous reporting to deriver.Because driver is responsible for scheduling, receiver received data if n

by receiver.Jobgenerator's startup results in every batchduration, calling Dstreamgraph to generate the Rdd Graph and generate the job.The line pool in Jobscheduler commits the encapsulated Jobset object (time value, Job, meta of the data source). The business logic is encapsulated in the job, causing the action of the last Rdd to be triggered, and the job is actually dispatched on the spark cluster by Dagscheduler.So it can be said that Jobscheduler

Java implementation Spark streaming and Kafka integration for streaming computing2017/6/26 added: Took over the search system, this six months have a lot of new experience, lazy change this vulgar text, we look at the comprehensive read this article New Boven to understand the following vulgar code, http://blog.csdn.net/yujishi2/article/details/73849237.

Spark StreamingSpark streaming uses the spark API for streaming calculations, which means that streaming and batching are done on spark. So you can reuse batch code, build powerful interactive applications using

Case-based running source for spark streamingNote: This lecture is based on the spark 1.6.1 version (the latest version of Spark in May 2016).Previous section ReviewIn the last lesson , we explored the

The main contents of this section:first, Dstream and A thorough study of the RDD relationshipA thorough study of the generation of StreamingrddSpark streaming Rdd think three key questions:The RDD itself is the basic object, according to a certain time to produce the Rdd of the object, with the accumulation of time, not its management will lead to memory overflow, so in batchduration time after performing the Rdd operation, the RDD needs to be managed

This course is based on the production and flow of real-time data, through the integration of the mainstream distributed Log Collection framework flume, distributed Message Queuing Kafka, distributed column Database HBase, and the current most popular spark streaming to create real-time stream processing project combat, Let you master real-time processing of the entire processing process, to reach the level
