我目前在flume中有这个配置

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

TwitterAgent.sources.Twitter.type= org.apache.flume.source.twitter.TwitterSource
TwitterAgent.sources.Twitter.channels = MemChannel
TwitterAgent.sources.Twitter.consumerKey=XXXXXXXXXXXX
TwitterAgent.sources.Twitter.consumerSecret=XXXXXXXXXXXX
TwitterAgent.sources.Twitter.accessToken=XXXXXXXXXXXX
TwitterAgent.sources.Twitter.accessTokenSecret=XXXXXXXXXXXX 

TwitterAgent.sources.Twitter.maxBatchSize=1000

TwitterAgent.sinks.HDFS.channel=MemChannel
TwitterAgent.sinks.HDFS.type= hdfs
TwitterAgent.sinks.HDFS.hdfs.path= hdfs://quickstart.cloudera:8020/user/flume/tweets

TwitterAgent.sinks.HDFS.hdfs.fileType = DataStream
TwitterAgent.sinks.HDFS.hdfs.writeFormat = Text
TwitterAgent.sinks.HDFS.hdfs.batchSize=10
TwitterAgent.sinks.HDFS.hdfs.rollSize=0
TwitterAgent.sinks.HDFS.hdfs.rollCount= 10000
TwitterAgent.sinks.HDFS.hdfs.rollInterval = 600

TwitterAgent.channels.MemChannel.type= memory
TwitterAgent.channels.MemChannel.capacity = 10000
TwitterAgent.channels.MemChannel.transactionCapacity =100

twitter应用程序验证密钥正确。我在flume日志文件中不断发现这个错误：

我在路径/home/cloudera/flumeprac上创建了twitter.conf文件
我正在终端上运行下面的命令

[cloudera@quickstart flumeprac]$ flume-ng agent --conf-file
 twitter.conf --name TwitterAgent --conf $FLUME_HOME/conf
 _DFflume.root.logger=INFO,console
