Question

我在this pipeline的帮助下收集推文。我尝试使用一些自己的脚本来分析收集的脚本。我发现我得到了多条同名的推文。我查看了hdfs：// user / flume / tweets，发现这多条推文都存储在文件中。所以它不是蜂巢或oozie问题。

可能是水槽问题：我在水槽参数中进行了一些编辑：

TwitterAgent.sinks.HDFS.hdfs.batchSize = 10000 //in github 1000
TwitterAgent.sinks.HDFS.hdfs.rollSize = 0
TwitterAgent.sinks.HDFS.hdfs.rollCount = 100000 //in github 10000

TwitterAgent.channels.MemChannel.type = memory
TwitterAgent.channels.MemChannel.capacity = 100000 //in github 10000
TwitterAgent.channels.MemChannel.transactionCapacity = 10000 //in github 100

或推特给这条推文？而且这不是hadoop问题吗？

这是我的水槽配置：

# The configuration file needs to define the sources, 
# the channels and the sinks.
# Sources, channels and sinks are defined per agent, 
# in this case called 'TwitterAgent'

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 = MyKey
 TwitterAgent.sources.Twitter.consumerSecret = MyKey
 TwitterAgent.sources.Twitter.accessToken = MyKey
 TwitterAgent.sources.Twitter.accessTokenSecret = MyKey
 TwitterAgent.sources.Twitter.keywords = hadoop, big-data , big data, analytics, bigdata, cloudera, data science, data scientiest, business intelligence, mapreduce, data warehouse, data warehousing, mahout, hbase, nosql, newsql, businessintelligence, cloudcomputing

 TwitterAgent.sinks.HDFS.channel = MemChannel
 TwitterAgent.sinks.HDFS.type = hdfs
 TwitterAgent.sinks.HDFS.hdfs.path = hdfs://rh-hadoop-master:8020/user/flume/tweets/%Y/%m/%d/%H/
 TwitterAgent.sinks.HDFS.hdfs.fileType = DataStream
 TwitterAgent.sinks.HDFS.hdfs.writeFormat = Text
 TwitterAgent.sinks.HDFS.hdfs.batchSize = 10000
 TwitterAgent.sinks.HDFS.hdfs.rollSize = 0
 TwitterAgent.sinks.HDFS.hdfs.rollCount = 100000

 TwitterAgent.channels.MemChannel.type = memory
 TwitterAgent.channels.MemChannel.capacity = 100000
 TwitterAgent.channels.MemChannel.transactionCapacity = 10000

此处有重复行的示例：
