Who is this presentation for?

  • Developers, IT professionals, and those working with a Hadoop cluster

Prerequisite knowledge

  • General experience working with a Hadoop cluster and securing sensitive data in Hadoop

What you'll learn

  • Understand why options other than Kerberos need to exist
  • Learn how SASL and JAAS give you more flexibility
  • Explore how to complete the picture with strong authorization, auditing, and data protection


Security will always be very important in the world of big data, but the choices today mostly start with Kerberos. Does that mean setting up security is always going to be painful? What if your company standardizes on other security alternatives? What if you want to have the freedom to decide what security type to support?

Yuliya Feldman and Bill ODonnell discuss your options. Frameworks like SASL (simple authentication and security layer) and JAAS (Java authentication and authorization service) let you plug in different security alternatives and even support multiple security types at the same time.

Topics include:

  • Why options other than Kerberos need to exist
  • How SASL and JAAS give you more flexibility
  • Completing the picture with strong authorization, auditing, and data protection
