title: Flume configuration to upload files with same name
body: <p>I have 10 files with some data varying in length.I would like to store corresponding data in same file and with same filename, but flume is splitting up the data and saving as FlumeData.timestamp. I am using the configuration as below:</p>
  
  <pre><code> a1.sources = r1
  a1.sinks =  k2
  a1.channels = c1
  
  a1.channels.c1.type = file
  a1.channels.c1.checkpointDir = /mnt/flume/checkpoint

  a1.channels.c1.backupCheckpointDir = /mnt/flume/backup
  a1.channels.c1.checkpointInterval = 2000
  a1.channels.c1.minimumRequiredSpace = 9000000
  
  a1.sources.r1.channels = c1
  a1.sources.r1.type = spooldir
  a1.sources.r1.spoolDir = /usr/local/netlog/
  a1.sources.r1.fileHeader = true
  a1.sources.r1.bufferMaxLineLength = 500
  a1.sources.r1.bufferMaxLines = 10000
  a1.sources.r1.batchSize = 100000
  #a1.sources.r1.deletePolicy = immediate
  
  a1.sinks.k2.type = hdfs
  a1.sinks.k2.channel = c1
  
  a1.sinks.k2.hdfs.filePrefix = %{file}
  a1.sinks.k2.hdfs.fileType = DataStream
  a1.sinks.k2.hdfs.batchSize = 100000
  a1.sinks.k2.hdfs.rollSize = 10000000
  a1.sinks.k2.hdfs.rollInterval = 0
  a1.sinks.k2.hdfs.rollSize = 0
  a1.sinks.k2.hdfs.rollCount = 0
  a1.sinks.k2.hdfs.idleTimeout = 0
  a1.sinks.k2.hdfs.writeFormat = Text
  a1.sinks.k2.hdfs.path = /user/flume
  
  # Bind the source and sink to the channel
  a1.sources.r1.channels = c1
  a1.sinks.k2.channel = c1
  </code></pre>
  
  <p>Kindly suggest how i can store same 10 files with same filename and data within it. File size can vary from 2 MB to 15 MB.</p>
  
  <p>The error i see in logs is</p>
