Flume supplies twitter data in avro format and not in Json.
Why?
Flume Config Agent:
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 = xxx
TwitterAgent.sources.Twitter.consumerSecret = xxx
TwitterAgent.sources.Twitter.accessToken = xxx
TwitterAgent.sources.Twitter.accessTokenSecret = xxx
TwitterAgent.sources.Twitter.maxBatchSize = 10
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
TwitterAgent.sinks.HDFS.hdfs.round = true
TwitterAgent.sinks.HDFS.hdfs.roundValue = 5
TwitterAgent.sinks.HDFS.hdfs.roundUnit = minute
TwitterAgent.sinks.HDFS.hdfs.useLocalTimeStamp = true
TwitterAgent.sinks.HDFS.hdfs.fileType = DataStream
TwitterAgent.sinks.HDFS.hdfs.writeFormat = Text
TwitterAgent.channels.MemChannel.type = memory

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.
Kind regards,
Karl
