In this chapter, we introduced Apache Hadoop and the various components, such as HDFS, YARN, and so on, that are part of a Hadoop cluster. We also saw the subcomponents of an HDFS and YARN cluster and how they interact with each other. Then we walked through how to set up a single node Hadoop cluster.
We also introduced Storm-YARN, which was the main point of this chapter. Storm-YARN enables you to run Storm topologies on a Hadoop cluster. This helps from a manageability and operations point of view. Finally, we saw how to deploy a topology on Storm running on YARN.
In the next chapter, we will see how Storm can integrate with other big data technologies, such as HBase, Redis, and so on.
