flume 使用 spool source的时候字符集出错

1. 错误所在

2016-04-21 02:23:05,508 (pool-3-thread-1) [ERROR - org.apache.flume.source.SpoolDirectorySource$SpoolDirectoryRunnable.run(SpoolDirectorySource.java:256)] FATAL: Spool Directory source source1: { spoolDir: /home/hadoop_admin/movielog/ }: Uncaught exception in SpoolDirectorySource thread.

2. 解决方法

　　原因的inputCharset属性的默认值UTF-8,但是所读取的日志文件的字符集却是GBK,所以更改一下这个属性值就可以了

agent1.sources = source1
agent1.channels = channel1
agent1.sinks = sink1

# For each one of the sources, the type is defined
agent1.sources.source1.type = spooldir
agent1.sources.source1.spoolDir =/home/hadoop_admin/movielog/
agent1.sources.source1.inputCharset = GBK
agent1.sources.source1.fileHeader = true
agent1.sources.source1.deletePolicy = immediate
agent1.sources.source1.batchSize = 1000
agent1.sources.source1.channels = channel1

# Each sink's type must be defined
agent1.sinks.sink1.type = hdfs
agent1.sinks.sink1.hdfs.path = hdfs://master:9000/flumeTest
agent1.sinks.sink1.hdfs.filePrefix = master-
agent1.sinks.sink1.hdfs.writeFormat = Text
agent1.sinks.sink1.hdfs.fileType = DataStream
agent1.sinks.sink1.hdfs.rollInterval = 0
agent1.sinks.sink1.hdfs.rollSize = 10240
agent1.sinks.sink1.hdfs.batchSize = 100
agent1.sinks.sink1.hdfs.callTimeout = 30000
agent1.sinks.sink1.channel = channel1

# Each channel's type is defined.
agent1.channels.channel1.type = memory
agent1.channels.channel1.capacity = 100000
agent1.channels.channel1.transactionCapacity = 100000
agent1.channels.channel1.keep-alive = 30
