Question

我已成功配置flume以将文本文件从本地文件夹传输到hdfs。我的问题是当这个文件被转移到hdfs时，我的文本文件中会添加一些不需要的文本“hdfs.write.Longwriter + binary characters”。这是我的flume.conf

agent.sources = flumedump
agent.channels = memoryChannel
agent.sinks = flumeHDFS

agent.sources.flumedump.type = spooldir
agent.sources.flumedump.spoolDir = /opt/test/flume/flumedump/
agent.sources.flumedump.channels = memoryChannel

# Each sink's type must be defined
agent.sinks.flumeHDFS.type = hdfs
agent.sinks.flumeHDFS.hdfs.path = hdfs://bigdata.ibm.com:9000/user/vin
agent.sinks.flumeHDFS.fileType = DataStream

#Format to be written
agent.sinks.flumeHDFS.hdfs.writeFormat = Text

agent.sinks.flumeHDFS.hdfs.maxOpenFiles = 10
# rollover file based on maximum size of 10 MB
agent.sinks.flumeHDFS.hdfs.rollSize = 10485760

# never rollover based on the number of events
agent.sinks.flumeHDFS.hdfs.rollCount = 0

# rollover file based on max time of 1 mi
agent.sinks.flumeHDFS.hdfs.rollInterval = 60


#Specify the channel the sink should use
agent.sinks.flumeHDFS.channel = memoryChannel

# Each channel's type is defined.
agent.channels.memoryChannel.type = memory

# Other config values specific to each type of channel(sink or source)
# can be defined as well
# In this case, it specifies the capacity of the memory channel
agent.channels.memoryChannel.capacity = 100

我的源文本文件非常简单，包含文字：嗨我的名字是Hadoop，这是文件一。

我在hdfs中获得的接收器文件如下所示： SEQ！org.apache.hadoop.io.LongWritableorg.apache.hadoop.io.Text 5 ＆gt; I＆lt;4H ǥ +嗨我的名字是Hadoop，这是档案一。

请让我知道我做错了什么？

想出来。我不得不修理这条线

agent.sinks.flumeHDFS.fileType = DataStream

并将其更改为

agent.sinks.flumeHDFS.hdfs.fileType = DataStream

这解决了这个问题。

sink.hdfs writer在我的文本文件中添加了垃圾
