我正在尝试使用flume和spooldir作为源和HDFS作为接收器将csv文件（6MB）加载到HDFS中，这是我的配置文件：
# Initialize agent's source, channel and sink
agent.sources = TwitterExampleDir
agent.channels = memoryChannel
agent.sinks = flumeHDFS
# Setting the source to spool directory where the file exists
agent.sources.TwitterExampleDir.type = spooldir
agent.sources.TwitterExampleDir.spoolDir = /usr/local/word_count_input
# Setting the channel to memory
agent.channels.memoryChannel.type = memory
# Max number of events stored in the memory channel
agent.channels.memoryChannel.capacity = 10000
# agent.channels.memoryChannel.batchSize = 15000
agent.channels.memoryChannel.transactioncapacity = 1000000
# Setting the sink to HDFS
agent.sinks.flumeHDFS.type = hdfs
agent.sinks.flumeHDFS.hdfs.path = hdfs://192.168.220.128:8000/spool5
agent.sinks.flumeHDFS.hdfs.fileType = DataStream
# Write format can be text or writable
agent.sinks.flumeHDFS.hdfs.writeFormat = Text
# use a single csv file at a time
agent.sinks.flumeHDFS.hdfs.maxOpenFiles = 1
# rollover file based on maximum size of 10 MB
agent.sinks.flumeHDFS.hdfs.rollCount = 0
agent.sinks.flumeHDFS.hdfs.rollInterval = 0
agent.sinks.flumeHDFS.hdfs.rollSize = 1000
agent.sinks.flumeHDFS.hdfs.batchSize = 100
# never rollover based on the number of events
agent.sinks.flumeHDFS.hdfs.rollCount = 0
# rollover file based on max time of 1 min
#agent.sinks.flumeHDFS.hdfs.rollInterval = 0
# agent.sinks.flumeHDFS.hdfs.idleTimeout = 600
# Connect source and sink with channel
agent.sources.TwitterExampleDir.channels = memoryChannel
agent.sinks.flumeHDFS.channel = memoryChannel
之后我得到了这些错误并且不知道为什么：

有谁可以帮我解决这个问题？
答案 0 :(得分：0)
我正在使用hortonworks sandbox v2.2，经过长时间的调试后，我发现手动安装的spark版本i与＃34; v1.2＆＃34;之间存在一些冲突。和hortonworks沙箱库，所以我决定使用cloudera quickstart 5.3.0，现在一切正常
