Flume-A：从网络端口采集数据输出到控制台

1概述

了解一个框架就去它的官网上看 http://flume.apache.org/
Flume is a distributed, reliable, and available service for efficiently collecting, aggregating, and moving large amounts of log data. It has a simple and flexible architecture based on streaming data flows. It is robust and fault tolerant with tunable reliability mechanisms and many failover and recovery mechanisms. It uses a simple extensible data model that allows for online analytic application.

使用：使用flume的关键就是写配置文件
A) 配置Source
B) 配置Channel
C) 配置Sink
D) 把它们串联起来

第一种方式：从网络端口采集数据输出到控制台

netcat source +memory channel +logger sink

# Name the components on this agent   定义这个Agent名称为a1,sources,sinks,channels名称为r1,k1,c1
a1.sources = r1
a1.sinks = k1
a1.channels = c1
