在将数据从本地路径复制到hdfs sink时，我在hdfs位置的文件中获得了一些垃圾数据。
我的flume配置文件：

# spool.conf: A single-node Flume configuration

# Name the components on this agent

a1.sources = s1
a1.sinks = k1
a1.channels = c1

# Describe/configure the source

a1.sources.s1.type = spooldir  
a1.sources.s1.spoolDir = /home/cloudera/spool_source    
a1.sources.s1.channels = c1   

# Describe the sink

a1.sinks.k1.type = hdfs
a1.sinks.k1.channel = c1
a1.sinks.k1.hdfs.path = flumefolder/events
a1.sinks.k1.hdfs.filetype = Datastream

# Format to be written

a1.sinks.k1.hdfs.writeFormat = Text

# Use a channel which buffers events in memory

a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

我正在将文件从本地路径“/home/cloudera/spool\u source”复制到hdfs路径“flumefolder/events”。
Flume命令：

flume-ng agent --conf-file spool.conf --name a1 -Dflume.root.logger=INFO,console

文件“salary.txt”位于本地路径“/home/cloudera/spool\u source”是：

GR1,Emp1,Jan,31,2500
GR3,Emp3,Jan,18,2630
GR4,Emp4,Jan,31,3000
GR4,Emp4,Feb,28,3000
GR1,Emp1,Feb,15,2500
GR2,Emp2,Feb,28,2800
GR2,Emp2,Mar,31,2800
GR3,Emp3,Mar,31,3000
GR1,Emp1,Mar,15,2500
GR2,Emp2,Apr,31,2630
GR3,Emp3,Apr,17,3000
GR4,Emp4,Apr,31,3200
GR7,Emp7,Apr,21,2500
GR11,Emp11,Apr,17,2000

在目标路径“flumefolder/events”处，使用垃圾值复制数据，如下所示：

1 W��ȩGR1,Emp1,Jan,31,2500W��ȲGR3,Emp3,Jan,18,2630W��ȷGR4,Emp4,Jan,31,3000W��ȻGR4,Emp4,Feb,28,3000W��ȽGR1,Emp1,Feb,15,2500W����GR2,Emp2,Feb,28,2800W����GR2,Emp2,Mar,31,2800W����GR3,Emp3,Mar,31,3000W����GR1,Emp1,Mar,15,2500W����GR2,Emp2,

我的配置文件spool.conf有什么问题，我无法找出原因。
