我是 Flume 的新手。我试图从 Twitter 中提取数据，但我没有成功。（我正在使用 Cloudera 快速入门）
我的 conf 文件如下所示：
TwitterAgent.sources = Twitter
TwitterAgent.channels = MemChannel
TwitterAgent.sinks = HDFS
TwitterAgent.sources.Twitter.type = com.cloudera.flume.source.TwitterSource
TwitterAgent.sources.Twitter.channels = MemChannel
我添加了所有这些取自 Twitter 帐户 consumerKey、consumerSecret、accessToken、accessTokenSecret、keywords 和 path 的值
TwitterAgent.sinks.HDFS.channel = MemChannel
TwitterAgent.sinks.HDFS.type = hdfs
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
我用来执行 conf 文件的命令是：
flume-ng agent --conf conf --conf-file flume.conf -Dflume.root.logger=DEBUG,console -name TwitterAgent
我得到的错误是：
18/06/27 12:17:18 WARN conf.FlumeConfiguration: Agent configuration for 'TwitterAgent' does not contain any valid channels. Marking it as invalid.
18/06/27 12:17:18 WARN conf.FlumeConfiguration: Agent configuration invalid for agent 'TwitterAgent'. It will be removed.
18/06/27 12:17:18 INFO conf.FlumeConfiguration: Post-validation flume configuration contains configuration for agents: []
18/06/27 12:17:18 WARN node.AbstractConfigurationProvider: No configuration found for this host:TwitterAgent
18/06/27 12:17:18 INFO node.Application: Starting new configuration:{ sourceRunners:{} sinkRunners:{} channels:{} }
请给我建议。
