Nowadays a typical Hadoop deployment consists of core Hadoop components – HDFS and MapReduce – several other components such as HBase, HttpFS, Oozie, Pig, Hive, Sqoop, Flume, plus programmatic integration from external systems and applications. This effectively creates a complex and heterogenous distributed environment that runs across several machines and uses different protocols to communicate with each other; all of which is used concurrently by several users and applications. When a Hadoop deployment and its ecosystem is used to process sensitive data (such as financial records, payment transactions, healthcare records), several security requirements arise. These security requirements may be dictated by internal policies and/or government regulations. They may require strong authentication, selective authorization to access data/resources, and data confidentiality. This session covers in detail how different components in the Hadoop ecosystem and external applications can interact with each other in a secure manner providing authentication, authorization, and confidentiality when accessing services and transferring data to/from/between services. The session will cover topics like Kerberos authentication, Web UI authentication, File System permissions, delegation tokens, Access Control Lists, ProxyUser impersonation and network encryption.
