Step 1: Install CDH 5
Cloudera strongly recommends that you set up a fully-functional CDH 5 cluster before you begin configuring it to use Hadoop's security features. When a secure Hadoop cluster is not configured correctly, the resulting error messages are in a preliminary state, so it's best to start implementing security after you are sure your Hadoop cluster is working properly without security.
For information about installing and configuring Hadoop and CDH 5 components, and deploying on a cluster, see the CDH 5 Installation Guide
