Hadoop And Active Directory

RK Kuppala explains how to integrate a Hadoop cluster with Active Directory:

This post explains kerberizing an existing Hadoop cluster using Ambari. Kerberos helps with the Authentication part of enterprise security (while authorization, auditing and data protection being the remaining parts).

HDP uses Kerberos, which is an industry standard for authenticate users and resources and providing strong identity for users. Apache Ambari can kerberize an existing cluster by using an existing MIT key distribution center (KDC) or Microsoft’s Active Directory.

This was a lot easier than I expected.
