Introduction to Kerberos Principals and Keytabs
Why Use Cloudera Manager to Implement Hadoop Security?
Procedure for Using Cloudera Manager to Configure Hadoop Security
Step 1: Install CDH and Cloudera Manager
Step 2: (CDH3 only) Install the CDH Security Packages
Step 3: Set up a Local KDC and Default Domain for the Hadoop Cluster
Step 4: If you are Using AES-256 Encryption, install the JCE Policy File
Step 5: Get or Create a Kerberos Principal and Keytab File for the Cloudera Manager Server
Step 6: Deploying the Cloudera Manager Server Keytab
Step 7: Configure the Kerberos Default Realm in the Cloudera Manager Admin Console
Step 8: Stop all Services
Step 9: Enable Hadoop Security
Step 10: Wait for the Generate Credentials command to finish
Step 11: Enable Hue to Work with Hadoop Security using Cloudera Manager
Step 12: (Flume Only) Use Substitution Variables for the Kerberos Principal and Keytab
Step 13: (CDH 4.0 and 4.1 only) Configure Hue to use a local Hive metastore
Step 14: Start all Services
Step 15: Create the hdfs Super User Principal
Step 16: Get or Create a Kerberos Principal or Keytab for Each User Account
Step 17: Prepare the Cluster for Each User
Step 18: Verify that Kerberos Security is Working
Step 19: (Optional) Enable Authentication for HTTP Web-Consoles for Hadoop Roles
