我正在尝试将Twitter提要流式传输到hdfs，然后使用配置单元。但是第一部分，将数据流传输并加载到hdfs无效，并给出了ParserException。
我已经下载了apache-flume-1.9.0-bin。所有内容都在/ usr / lib /
已移至conf /目录。我将文件flume-env.sh.template复制为flume-env.sh，然后将JAVA_HOME编辑到我的Java路径/usr/lib/jvm/java-1.8.0-openjdk-amd64
我创建了twitter.conf，如下所示：
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 = BOIDeKDOluUI6D2cN0GkdaM3Z
TwitterAgent.sources.Twitter.consumerSecret = hVDpBQbFOWk6sYGSLAhRrmVUT9mN3LCGONosx4nIqiiGeGfoMZ
TwitterAgent.sources.Twitter.accessToken = 1137972756828499968-xGItReLqUsQy0aIcP4aCHVC3HGuGtY
TwitterAgent.sources.Twitter.accessTokenSecret = rAb1IVakREloLFpPhGSBTp8tlfTutZnPWxridanQ2gdW1
TwitterAgent.sources.Twitter.keywords = hadoop, bigdata, cricket, worlcup
TwitterAgent.sinks.HDFS.channel = MemChannel
TwitterAgent.sinks.HDFS.type=hdfs
TwitterAgent.sinks.HDFS.hdfs.path = hdfs://localhost:9000/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
TwitterAgent.sinks.HDFS.hdfs.rollInterval = 600
TwitterAgent.channels.Memchannel.type = memory
TwitterAgent.channels.Memchannel.capacity = 10000
TwitterAgent.channels.Memchannel.transactionCapacity = 1000
TwitterAgent.sources.Twitter.channels=MemChannel
TwitterAgent.sinks.HDFS.channel=MemChannel
我已经运行了以下命令： bin / flume-ng代理--conf conf --conf-file twitter.conf --name TwitterAgent -Dflume.root.logger = INFO，控制台
我得到的错误是：

为什么要一次又一次检查更改？
是否没有TwitterAgent的配置文件？
