SAS Users
Providing technical tips and support information, written for and by SAS users.
The only thing that’s constant is change. The continual cycle of computing changes leads to common questions about the effects of these changes—operating systems are getting upgraded, customers are moving to new SAS clients, upgrading to new releases of SAS, working with new Java and browser versions. All of these
In previous posts, we’ve shared the importance of understanding the fundamentals of Kerberos authentication and how we can simplify processes by placing SAS and Hadoop in the same realm. For SAS applications to interact with a secure Hadoop environment, we must address the third key practice: Ensure Kerberos prerequisites are met
When SAS is used for analysis on large volumes of data (in the gigabytes), SAS reads and writes the data using large block sequential IO. To gain the optimal performance from the hardware when doing these IOs, we strongly suggest that you review the information below to ensure that the
Report design includes several phases. Granted, these phases aren’t official: they’re more a reflection of my own thought processes and how my report designs typically unfold: the initial “get the data on the screen to see what we have” phase the addition of filters and prompts to assist with guided
So, with the simple introduction in Understanding Hadoop security, configuring Kerberos with Hadoop alone looks relatively straightforward. Your Hadoop environment sits in isolation within a separate, independent Kerberos realm with its own Kerberos Key Distribution Center. End users can happily type commands as they log into a machine hosting the
Last year, after 15 years of benefiting from the SAS community, I thought it was time to give a little something back. So I decided to write a paper on two technologies I have a healthy interest in: SAS and Hadoop. My paper SASReduce: an implementation of MapReduce using BASE/SAS
