让你系统认识flume及安装和使用flume1.5传输数据到hadoop2.2

我们走到这一步，我们会想到一个问题，我的电脑是32位的，不知道能否安装？如果我的电脑是64位的，能否安装。之前我们装的hadoop就分为32位和64位，想到这个问题是正常的，但是这里不用担心，因为我们下载的是二进制包，也就是说你32位和64位都可以安装。

agent1表示代理名称
agent1.sources=source1
agent1.sinks=sink1
agent1.channels=channel1


#配置source1
agent1.sources.source1.type=spooldir
agent1.sources.source1.spoolDir=/usr/aboutyunlog
agent1.sources.source1.channels=channel1
agent1.sources.source1.fileHeader = false

#配置sink1
agent1.sinks.sink1.type=hdfs
agent1.sinks.sink1.hdfs.path=hdfs://master:8020/aboutyunlog
agent1.sinks.sink1.hdfs.fileType=DataStream
agent1.sinks.sink1.hdfs.writeFormat=TEXT
agent1.sinks.sink1.hdfs.rollInterval=4
agent1.sinks.sink1.channel=channel1


#配置channel1
agent1.channels.channel1.type=file
agent1.channels.channel1.checkpointDir=/usr/aboutyun_tmp123
agent1.channels.channel1.dataDirs=/usr/aboutyun_tmp

flume-ng agent -n agent1 -c conf -f usr/flume/conf/example -Dflume.root.logger=DEBUG,console

注意：这个不要关闭，我们另外开启一个shell，在监控文件夹中放入要上传的文件
