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$SpoolDirectoryRunnable.run(SpoolDirectorySource.java:256)] FATAL: Spool Directory source r1: { spoolDir: /home/hadoop/flumeSpool-2 }: Uncaught exception in SpoolDirectorySource thread. Restart or reconfigure Flume to continue processing.
- java.nio.charset.MalformedInputException: Input length = 1
- at java.nio.charset.CoderResult.throwException(CoderResult.java:281)
- at org.apache.flume.serialization.ResettableFileInputStream.readChar(ResettableFileInputStream.java:195)
实验二
读取数字和”；“符号的TXT文档
报错
- 2015-11-06 22:22:49,012 (pool-3-thread-1) [ERROR - org.apache.flume.source.SpoolDirectorySource$SpoolDirectoryRunnable.run(SpoolDirectorySource.java:256)] FATAL: Spool Directory source r1: { spoolDir: /home/hadoop/flumeSpool-3 }: Uncaught exception in SpoolDirectorySource thread. Restart or reconfigure Flume to continue processing.
- java.nio.charset.MalformedInputException: Input length = 1
- at java.nio.charset.CoderResult.throwException(CoderResult.java:281)
- at org.apache.flume.serialization.ResettableFileInputStream.readChar(ResettableFileInputStream.java:195)
此报错与前面的报错相同。
实验三
读取数字和”回车符“的TXT文档
报错：
- 2015-11-06 22:28:06,889 (pool-3-thread-1) [ERROR - org.apache.flume.source.SpoolDirectorySource$SpoolDirectoryRunnable.run(SpoolDirectorySource.java:256)] FATAL: Spool Directory source r1: { spoolDir: /home/hadoop/flumeSpool-7 }: Uncaught exception in SpoolDirectorySource thread. Restart or reconfigure Flume to continue processing.

- at java.nio.charset.CoderResult.throwException(CoderResult.java:281)
- at org.apache.flume.serialization.ResettableFileInputStream.readChar(ResettableFileInputStream.java:195)
实验四
读取数字，字母，汉字组成的csv文件
报错：
- 2015-11-06 22:40:34,781 (pool-3-thread-1) [ERROR - org.apache.flume.source.SpoolDirectorySource$SpoolDirectoryRunnable.run(SpoolDirectorySource.java:256)] FATAL: Spool Directory source r1: { spoolDir: /home/hadoop/flumeSpool-6 }: Uncaught exception in SpoolDirectorySource thread. Restart or reconfigure Flume to continue processing.

实验五
读取数字和汉字组成的TXT文件
报错：
- 2015-11-06 23:34:29,455 (pool-3-thread-1) [ERROR - org.apache.flume.source.SpoolDirectorySource$SpoolDirectoryRunnable.run(SpoolDirectorySource.java:256)] FATAL: Spool Directory source r1: { spoolDir: /home/hadoop/flumeSpool-10 }: Uncaught exception in SpoolDirectorySource thread. Restart or reconfigure Flume to continue processing.

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“。
