把Flume的Source设置为Spooling directory source，在设定的目录下放置需要读取的文件，一些文件在读取过程中会报错。

文件格式和报错如下：

实验一

读取汉子和“；"符号的TXT文档

会报一下错误

2015-11-06 22:16:02,386 (pool-3-thread-1) [ERROR - org.apache.flume.source.SpoolDirectorySource$SpoolDirectoryRunnable.run(SpoolDirectorySource.java:256)] FATAL: Spool Directory source r1: { spoolDir: /home/hadoop/flumeSpool-2 }: Uncaught exception in SpoolDirectorySource thread.

实验二

读取数字和”；“符号的TXT文档

报错

成功的实验一

一排数字，什么符号都没有

成功的实验二

如上所示，不缺定是否使用了”回车符“。
