Configuring Hadoop Security with Cloudera Manager
This guide describes how to use Cloudera Manager to automate many of the manual tasks of implementing Kerberos security on your CDH cluster.
- Background - These instructions assume you know how to install and configure Kerberos, you already have a working Kerberos key distribution center (KDC) and realm setup, and that you've installed the Kerberos user packages on all cluster hosts and hosts that will be used to access the cluster.
