水槽加載csv文件擅長hdfs水槽

Question

我已經配置我的Flume源是類型Spooldir。我有很多CSV文件，.xl3和.xls，我希望我的Flume代理將所有文件從spooldir加載到HDFS接收器。然而水槽代理回報例外

這是我水槽源配置：

agent.sources.s1.type = spooldir 
agent.sources.s1.spoolDir = /my-directory 
agent.sources.s1.basenameHeader = true 
agent.sources.batchSize = 10000 

和我的HDFS下沉：

agent.sinks.sk1.type = hdfs 
agent.sinks.sk1.hdfs.path = hdfs://...:8020/user/importflume/%Y/%m/%d/%H 
agent.sinks.sk1.hdfs.filePrefix = %{basename} 
agent.sinks.sk1.hdfs.rollSize = 0 
agent.sinks.sk1.hdfs.rollCount = 0 
agent.sinks.sk1.hdfs.useLocalTimeStamp = true 
agent.sinks.sk1.hdfs.batchsize = 10000 
agent.sinks.sk1.hdfs.fileType = DataStream 
agent.sinks.sk1.serializer = avro_event 
agent.sinks.sk1.serializer.compressionCodec = snappy

您可以使用卷軸目錄下面的配置。只需在下面的配置中給出本地文件系統和HDFS位置的路徑即可。

#Flume Configuration Starts 
# Define a file channel called fileChannel on agent1 
agent1.channels.fileChannel1_1.type = file 
# on linux FS 
agent1.channels.fileChannel1_1.capacity = 200000 
agent1.channels.fileChannel1_1.transactionCapacity = 1000 
# Define a source for agent1 
agent1.sources.source1_1.type = spooldir 
# on linux FS 
#Spooldir in my case is /home/hadoop/Desktop/flume_sink 
agent1.sources.source1_1.spoolDir = 'path' 
agent1.sources.source1_1.fileHeader = false 
agent1.sources.source1_1.fileSuffix = .COMPLETED 
agent1.sinks.hdfs-sink1_1.type = hdfs 

#Sink is /flume_import under hdfs 

agent1.sinks.hdfs-sink1_1.hdfs.path = hdfs://'path' 
agent1.sinks.hdfs-sink1_1.hdfs.batchSize = 1000 
agent1.sinks.hdfs-sink1_1.hdfs.rollSize = 268435456 
agent1.sinks.hdfs-sink1_1.hdfs.rollInterval = 0 
agent1.sinks.hdfs-sink1_1.hdfs.rollCount = 50000000 
agent1.sinks.hdfs-sink1_1.hdfs.writeFormat=Text 

agent1.sinks.hdfs-sink1_1.hdfs.fileType = DataStream 
agent1.sources.source1_1.channels = fileChannel1_1 
agent1.sinks.hdfs-sink1_1.channel = fileChannel1_1 

agent1.sinks = hdfs-sink1_1 
agent1.sources = source1_1 
agent1.channels = fileChannel1_1
