# (c) copyright 2014 martin lurie sample code not supported ( Do not copy and paste this script! It contains unprintable characters that are pretending to be spaces. The comments are designed to explain what is going on inline. The script goKerberos_beforeCM.sh does all the setup work for the Kerberos server and the appropriate configuration parameters. Give this script some time to run, it has to restart the cluster. Start up the VM and activate Cloudera Manager as shown here: You can get by with a little less RAM, but we will have everything including the Kerberos server running on one node. The Java Cryptography Extension (JCE) file from Oracleīefore you start the QuickStart VM, increase the memory allocation to 8GB RAM and increase the number of CPUs to two.The QuickStart VM, along with a corresponding VM runtime environment.You need the following downloads to follow along. If you want to read the product documentation, it’s available here. You should consider this reference material I’d suggest reading it later to understand more details about what the scripts do.

Taming the three-headed dog that guards the gates of Hades is challenging, so Cloudera has put significant effort into making this process easier in Hadoop-based enterprise data hubs. In this post, you’ll learn how to stand-up a one-node cluster with Kerberos enforcing user authentication, using the Cloudera QuickStart VM as a demo environment. Once users are authenticated, you can use projects like Apache Sentry (incubating) for role-based access control via GRANT/REVOKE statements. With Kerberos enabled, user authentication is required. Kerberos is the foundation of securing your Apache Hadoop cluster. Use the scripts and screenshots below to configure a Kerberized cluster in minutes.
