We've been working with several customers running Cloudera for their Hadoop projects helping them to integrate their Hadoop clusters into Active Directory. This integration guide will show you how to integrate Cloudera clusters into Active Directory, so that you can control user access to the cluster. 

Centrify Server Suite provides Identity, Access and Privilege Management for Cloudera:

• Simplifying AD integration for Cloudera
• Automating service account credential lifecycle management
• Simplifying access with AD-based user single sign-on authentication
• Ensuring regulatory compliance with least privilege and auditing
• Developer SDKs for secure client application access to Hadoop
