> TwitterAgent.sinks = HDFS
> TwitterAgent.sources.Twitter.type =
> org.apache.flume.source.twitter.TwitterSource

> TwitterAgent.sources.Twitter.maxBatchDurationMillis = 200
> TwitterAgent.sources.Twitter.keywords = United Nations
> TwitterAgent.sources.Twitter.deserializer.schemaType = LITERAL
> # HDFS Sink
> TwitterAgent.sinks.HDFS.channel = MemChannel
> TwitterAgent.sinks.HDFS.type = hdfs
> TwitterAgent.sinks.HDFS.hdfs.path = /demo/tweets/stream/%y-%m-%d/%H%M%S
> TwitterAgent.sinks.HDFS.hdfs.filePrefix = events

> By loading this twitter data into a HDFS table. It is not possible to convert
> with avro-tools-1.7.7.jar. into Json. We get error message: "No data"
> If we want to read this file we get following error message:
> "java -jar avro-tools-1.7.7.jar tojson twitter.avro > twitter.json
> Exception in thread "main" org.apache.avro.AvroRuntimeException:
> java.io.EOFException"
> I hope you could help us.
