Learn how to execute a WordCount algorithm which operates on a data-stream instead of bound data.
- [Voiceover] So we've talked a lot about stream processing,…but we haven't really seen it in action yet.…So, I thought now we could run the built in word count…algorithm on a data stream.…Now that data stream here is going to come…from a file that we create.…So I want to make sure that I am in the directory…where I extracted Kafka earlier, so I'll just take a look.…Not there, so I'll go over to that directory.…Now I'm going to create a file in here,…which just has a few lines on it.…And I'm just going to pipe that out to you,…a new file called file dash input.…
From there what I need to do is create a new topic…that I'm going to use for my stream processing.…And I'm going to do this using the Kafka…Topics Script, which comes with it.…I'll tell it to create it where ZooKeeper's running…the replication factor of one in partitions of one.…I'm not really worried about the replication here,…just want to illustrate how this word count algorithm works.…Then for a name I'll call it streams-file-input.…So I'll just copy this into the command line here.…
