im learning hadoop, flume etc and one of the projects I started was sentiment analysis, which is OK but now im trying to expand by collecting multiple sets of data, this is my flume.conf:
TwitterAgent.sources = Twitter
TwitterAgent.channels = MemChannel
TwitterAgent.sinks = HDFS HDFS2
TwitterAgent.sources.Twitter.type = com.cloudera.flume.source.TwitterSource
TwitterAgent.sources.Twitter.channels = MemChannel
TwitterAgent.sources.Twitter.consumerKey = xxx
TwitterAgent.sources.Twitter.consumerSecret = xxxx
TwitterAgent.sources.Twitter.accessToken = xxx
TwitterAgent.sources.Twitter.accessTokenSecret = xxxx
TwitterAgent.sources.Twitter.keywords = bbc
TwitterAgent.sinks.HDFS.channel = MemChannel
TwitterAgent.sinks.HDFS.type = hdfs
TwitterAgent.sinks.HDFS.hdfs.path = hdfs://xxx:8020/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.channels.MemChannel.type = memory
TwitterAgent.channels.MemChannel.capacity = 10000
TwitterAgent.channels.MemChannel.transactionCapacity = 100
what im hoping to achieve is put all tweets about bbc in the above location but also use the following config to put tweets about liverpool into a seperate folder:
TwitterAgent.sources.Twitter.keywords = liverpool
TwitterAgent.sinks.HDFS2.channel = MemChannel
TwitterAgent.sinks.HDFS2.type = hdfs
TwitterAgent.sinks.HDFS2.hdfs.path = hdfs://xxx:8020/user/flume/tweets/liverpool/
TwitterAgent.sinks.HDFS2.hdfs.fileType = DataStream
TwitterAgent.sinks.HDFS2.hdfs.writeFormat = Text
TwitterAgent.sinks.HDFS2.hdfs.batchSize = 1000
TwitterAgent.sinks.HDFS2.hdfs.rollSize = 0
TwitterAgent.sinks.HDFS2.hdfs.rollCount = 10000
TwitterAgent.channels.MemChannel2.type = memory
TwitterAgent.channels.MemChannel2.capacity = 10000
TwitterAgent.channels.MemChannel2.transactionCapacity = 10
This isnt working and I cant work out why, can anyone point me in the right direction?
