原因：
重复使用了同一个数据文件
解决方案1：
更改flume的配置文件conf的目录
a1.sources.r1.spoolDir = /usr/local/data/flumedata

#push mode
a1.sources = r1
a1.sinks = k1
a1.channels = c1
#source
a1.sources.r1.channels = c1
a1.sources.r1.type = spooldir
a1.sources.r1.spoolDir = /usr/local/data/flumedata
a1.sources.r1.fileHeader = true
#channel
a1.channels.c1.type =memory
a1.channels.c1.capacity = 20000
a1.channels.c1.transactionCapacity=5000
#sinks
a1.sinks.k1.channel = c1
a1.sinks.k1.type = avro
a1.sinks.k1.hostname=192.168.13.24
a1.sinks.k1.port = 9999
a1.sinks.k1.batchSize= 2000  

 

解决方案2：
在flume配置文件的目录下重新定义数据文件
