Chapter 4. Securing the Hadoop Ecosystem
In Chapter 3, Setting Up a Secured Hadoop Cluster, we looked at how to set up Kerberos authentication for HDFS and MapReduce components within a secured Hadoop cluster. But in our secured Big Data journey, this is only half done. The Hadoop ecosystem consists of various components such as Hive, Oozie, and HBase. We need to secure all the other Hadoop ecosystem components. In this chapter, we will look at the each of the ecosystem components and the various security challenges for each of these components, and how to set up secured authentication and user authorization for each of them.
Each ecosystem component has its own security challenges and needs to be configured uniquely based on its architecture to secure them. Each of these ecosystem components has end users directly accessing the component or a backend service accessing the Hadoop core components (HDFS and MapReduce).
The following are the topics that we'll be covering in this chapter:
