Flume学习12_Flume Spooling directory source读取文件格式的要求

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.

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：

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“。
