报错：
用命令启动：bin/flume-ng agent --conf ./conf/ -f conf/ flume-conf.conf -n agent1
一切正常，而且flume.log日志也正常。
用bin/flume-ng avro-client -H kf-app1 -p 44444 -F /chunk1/demo/flume/test2.txt发送文件，flume.log如下：
[demoe3base@kf-app1 logs]$ tail -f flume.log

问题来了：1、为什么是“FlumeData.1367994886244.tmp”临时文件，而不能将文件关闭呢？当我把代理强行kill掉或者关掉后，日志才打印出“08 五月 2013 14:21:17,556 INFO [hdfs-hdfssink1-call-runner-5] (org.apache.flume.sink.hdfs.BucketWriter.renameBucket:379) - Renaming hdfs://kf-app1:8020/flume/FlumeData.1367993804350.tmp to hdfs://kf-app1:8020/flume/FlumeData.1367993804350”，难道说代理不能够自动关闭？
2、而且在发送第二个文件后发现日志报错UNBOUND,难道说一个通道直接接收一个文件？

解决方法：
將8082改爲9000
.
