Flume not processing keywords from Twitter source with flume-ng with Hadoop 2.5 cdh5.3

I am trying to process some twitter keywords with MemChannel and HDFS. But flume-ng is not showing further progress after HDFS started status on the console.

Here are /etc/flume-ns/conf/flume-env.sh file contents.

Here are the twitter configuration file contents.

I am running below command on centOs console.

flume-ng agent -c /etc/flume-ng/conf -f /etc/flume-ng/conf/twitter.conf -n TwitterAgent -Dflume.root.logger=INFO,console

When I run the command here is the output.

You are missing ".sources" property of the agent. How can Flume-ng work without knowing the source? You are missing following line.

TwitterAgent.sources = Twitter

See source, channel and sink relationship diagram.

To see more detail, see following link: https://flume.apache.org/FlumeUserGuide.html

Always remember there are mainly three things in flume configuration file.( sources, channels, sinks ). First three lines are setting these three properties.

TwitterAgent.sources = Twitter
TwitterAgent.sinks = HDFS
TwitterAgent.channels = MemChannel

Rest of the configuration file is setting detailed properties of these three main things (sources, channels, sinks).

Check below corrected configuration file contents.

TwitterAgent.sources = Twitter
TwitterAgent.channels = MemChannel
TwitterAgent.sinks = HDFS

#TwitterAgent.sources.Twitter.type = com.cloudera.flume.source.TwitterSource
TwitterAgent.sources.Twitter.type = org.apache.flume.source.twitter.TwitterSource
TwitterAgent.sources.Twitter.channels = MemChannel

TwitterAgent.sources.Twitter.consumerKey = xxxxx
TwitterAgent.sources.Twitter.consumerSecret = xxxxxx
TwitterAgent.sources.Twitter.accessToken = xxxxx
TwitterAgent.sources.Twitter.accessTokenSecret = xxxxx

TwitterAgent.sources.Twitter.keywords = hadoop, 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://uat.cloudera:8020/user/root/flume/
    TwitterAgent.sinks.HDFS.hdfs.fileType = DataStream
TwitterAgent.sinks.HDFS.hdfs.writeFormat = Text
TwitterAgent.sinks.HDFS.hdfs.batchSize = 10
TwitterAgent.sinks.HDFS.hdfs.rollSize = 0
TwitterAgent.sinks.HDFS.hdfs.rollCount = 10

TwitterAgent.channels.MemChannel.type = memory
TwitterAgent.channels.MemChannel.capacity = 10
TwitterAgent.channels.MemChannel.transactionCapacity = 10

Other than setting sources property, I have also changed the below properties, so that we can quickly see the results on hdfs as temp files.

TwitterAgent.sinks.HDFS.hdfs.batchSize = 10
TwitterAgent.sinks.HDFS.hdfs.rollCount = 10
TwitterAgent.channels.MemChannel.capacity = 10
TwitterAgent.channels.MemChannel.transactionCapacity = 10

Copy the contents and save in any configuration file e.g sample.conf in /etc/flume-ng/conf/ folder and then use below command.

flume-ng agent -c /etc/flume-ng/conf -f /etc/flume-ng/conf/sample.conf -n TwitterAgent -Dflume.root.logger=INFO,console

After HDFS Started status, it should show processing message like this.
