A/Flume data flow model Flume event is defined as a data flow unit with byte payload and optional string properties, and the Flume agent is the JVM process that hosts the components of an event from the external source to the next destination. The following figure is the flume agent flowchart

Recently, in the Test Flume combines Kafka with spark streaming experiments. Today, the simple combination of flume and spark to make a record here, to avoid users detours. There are not thoughtful places also want to pass by the great God a lot of advice.The experiment is relatively simple, divided into two parts: first, Use avro-client send data two, Use Netcat Send Datafirst the Spark program requires Tw

First of all, Flume and Kafka are message systems , but they also have a lot of different places, flume more toward the message acquisition system, and Kafka more toward the message cache system. The difference in "one" designFlume is a message acquisition system, which mainly solves the problem is the multiple collection of messages. As a result, Flume provides

Flume is a real-time message collection system, it defines a variety of source, channel, sink, can be selected according to the actual situation.Flume Download and Documentation:http://flume.apache.org/KafkaKafka is a high-throughput distributed publish-subscribe messaging system that has the following features: Provides persistence of messages through the disk data structure of O (1), a structure that maintains long-lasting performance even

In the flume-based log collection system (a) architecture and design, we detail the architecture design of the flume-based log collection system and why it is designed. In this section, we will describe the problems encountered in the actual deployment and use process, the functional improvements to flume, and the optimizations that are made to the system.1 Summa
