我正在嘗試使用Flume進行推特分析。爲了從Twitter獲取推文，我已經在flume.conf文件中設置了所有必需的參數（consumerKey，consumerSecret，accessToken和accessTokenSecret）。異常如下 - org.apache.flume.FlumeException：無法加載源類型：com.cloudera.flume
TwitterAgent.sources = Twitter
TwitterAgent.channels = MemChannel
TwitterAgent.sinks = HDFS
TwitterAgent.sources.Twitter.type = com.cloudera.flume.source.TwitterSource
TwitterAgent.sources.Twitter.channels = MemChannel
TwitterAgent.sources.Twitter.consumerKey = xxxxxxxxxxxxxxxxxxxxxxxxxx
TwitterAgent.sources.Twitter.consumerSecret = xxxxxxxxxxxxxxxxxxxxxxxxxx
TwitterAgent.sources.Twitter.accessToken = xxxxxxxxxxxxxxxxxxxxxxxxxx
TwitterAgent.sources.Twitter.accessTokenSecret = xxxxxxxxxxxxxxxxxxxxxxxxxx
TwitterAgent.sources.Twitter.keywords = hadoop,opensource,iamsrk,onairwithaib,ihrithik
TwitterAgent.sinks.HDFS.channel = MemChannel
TwitterAgent.sinks.HDFS.type = hdfs
TwitterAgent.sinks.HDFS.hdfs.path = hdfs://localhost:8020/elections/tweets/%Y/%m/%d/%H/
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.channels.MemChannel.type = memory
TwitterAgent.channels.MemChannel.capacity = 10000
TwitterAgent.channels.MemChannel.transactionCapacity = 100
在flume-env.sh
export JAVA_HOME=/usr/lib/jvm/java-7-oracle
FLUME_CLASSPATH="home/nick/Downloads/apache-flume-1.6.0-bin/lib/flume-sources-1.0-SNAPSHOT.jar"
的Classpath當我運行水槽劑
`apache-flume-1.6.0-bin/bin$` ./flume-ng agent -n TwitterAgent -c conf -f ../conf/twitter.conf

任何人都可以說出爲什麼當我設置水槽source.jar已經引發此錯誤請幫我解決這個問題。
