本地文件到通过flume到hdfs

建立Linux目录

[root@hadoop11 app]# mkdir /usr/app/flumelog/dir 
[root@hadoop11 app]# mkdir /usr/app/flumelog/dir/logdfs 
[root@hadoop11 app]# mkdir /usr/app/flumelog/dir/logdfstmp 
[root@hadoop11 app]# mkdir /usr/app/flumelog/dir/logdfstmp/point

建立Hadoop目录

[root@hadoop11 app]#hadoop fs -mkdir /user/yuhui/flume

启动配置文件

flume-ng agent -n agent1 -c conf -f ./flume-dirTohdfs.properties
-Dflume.root.logger=DEBUG,console >./flume1.log 2>&1 &

查看启动进程： 

建立数据测试 

查看hdfs数据测试路径没有数据 

将测试数据放入监控路径，Flume读完数据之后，文件会自动更名 

查看hdfs数据测试路径，Flume输出的数据 

备注 
日志监控路径，只要日志放入则被Flume监控 
[root@hadoop11 app]# mkdir /usr/app/flumelog/dir/logdfs

日志读取完毕存储路径，日志在这里则一直存储在Channel中（最多只有两个log-number日志，且默认达到1.6G之后删除前面一个log，建立新的log） 
[root@hadoop11 app]# mkdir /usr/app/flumelog/dir/logdfstmp

日志监控路径中文件的路径存放点 
[root@hadoop11 app]# mkdir /usr/app/flumelog/dir/logdfstmp/point
