如果你已经设定了 hadoop home 在 .bashrc 作为

export HADOOP_HOME=<Path to your hadoop home>

那你就不需要了 localhost:9000 在下面

TwitterAgent.sinks.HDFS.hdfs.path = hdfs://localhost:9000/user/flume/tweets/

所以正确的路线应该是

TwitterAgent.sinks.HDFS.hdfs.path = hdfs:///user/flume/tweets/

考虑到twitter.conf如下所示，它应该可以工作

# Naming the components on the current agent.

    TwitterAgent.sources = Twitter 
    TwitterAgent.channels = MemChannel 
    TwitterAgent.sinks = HDFS

    # Describing/Configuring the source 
    TwitterAgent.sources.Twitter.type = org.apache.flume.source.twitter.TwitterSource
    TwitterAgent.sources.Twitter.consumerKey = Your OAuth consumer key
    TwitterAgent.sources.Twitter.consumerSecret = Your OAuth consumer secret 
    TwitterAgent.sources.Twitter.accessToken = Your OAuth consumer key access token 
    TwitterAgent.sources.Twitter.accessTokenSecret = Your OAuth consumer key access token secret 
    TwitterAgent.sources.Twitter.keywords = tutorials point,java, bigdata, mapreduce, mahout, hbase, nosql

    # Describing/Configuring the sink 

    TwitterAgent.sinks.HDFS.type = hdfs 
    TwitterAgent.sinks.HDFS.hdfs.path = hdfs:///user/flume/tweets/
    TwitterAgent.sinks.HDFS.hdfs.fileType = DataStream 
    TwitterAgent.sinks.HDFS.hdfs.writeFormat = Text 
    TwitterAgent.sinks.HDFS.hdfs.batchSize = 1000
    TwitterAgent.sinks.HDFS.hdfs.rollSize = 0 
    TwitterAgent.sinks.HDFS.hdfs.rollCount = 10000 

    # Describing/Configuring the channel TwitterAgent.channels.MemChannel.type = memory 
    TwitterAgent.channels.MemChannel.capacity = 10000 
    TwitterAgent.channels.MemChannel.transactionCapacity = 100

    # Binding the source and sink to the channel 
    TwitterAgent.sources.Twitter.channels = MemChannel
    TwitterAgent.sinks.HDFS.channel = MemChannel 

    TwitterAgent.channels.MemChannel.type=memory

您的命令应该类似于 Flume 家

bin/flume-ng agent --conf ./conf/ -f conf/twitter.conf Dflume.root.logger=DEBUG,console -n itterAgent
