In part 1 of this post, we looked at setting up Spark jobs from Cloud Analytics Services (CAS) to load and save data to and from Hadoop. Now we are moving on to the next step in the analytic cycle, scoring data in Hadoop and executing SAS code as a
This article is not a tutorial on Hadoop, Spark, or big data. At the same time, no prerequisite knowledge of these technologies is required for understanding. We’ll give you enough background prior to diving into the details. In simplest terms, the Hadoop framework maintains the data and Spark controls and
In his article How to use CASL to develop and work with user-defined CAS actions, Brian Kinnebrew defines CASL as "a language specification used by the SAS client to interact with and provide easy access to Cloud Analytic Services (CAS). CASL is a statement-based scripting language with many uses and
For every project in SAS®, the first step is almost always making your data available. This blog shows you how to load three of the most common input data types—a data set, a text file, and a Microsoft Excel file—into SAS® Cloud Analytic Services (CAS) tables. The three methods that
Did you know that you can run Lua code within Base SAS? Learn more about what PROC LUA can do through some examples.
In the article Serverless functions and SAS Viya - a good match I discussed using serverless functions to deliver SAS Viya applications. Ignoring all the buzz words, a serverless function boils down to a set of REST APIs. So, if you tried the example you are now a REST API
Recently, you may have heard about the release of the new SAS Cloud. The platform allows fast access to data-science applications in the cloud! Running on the SAS Cloud and using the latest container technology, SAS Cloud eliminates the need to install, update, or maintain software or related infrastructure. SAS
Also celebrating is your bank's branch manager. She was skeptical when headquarters analysts equipped branches for "Cloud-based application using SAS" , saying it would speed up loan applications. But your quick, frictionless transaction proved them right.The bank's accountants are happy too. The new pay-as-you-go mode of using SAS software in
Multi-tenancy is one of the exciting new capabilities of SAS Viya. Because it is so new, there is quite a lot of misinformation going around about it. I would like to offer you five key things to know about multi-tenancy before implementing a project using this new paradigm. All tenants
Prior to distributed DATA Step, DATA Step programmers never had to think about achieving repeatable results because DATA Step ran single-threaded and the source SAS7BDAT dataset was stored on disk. But if you need to obtain repeatable results in DATA Step code that runs distributed in CAS, this post provides a workaround that you'll want to keep handy.
This blog post outlines how to create your own CAS functions using the CAS Language. It also includes a partial list of both CASL built-in and common functions for reference.
You can communicate with various clients (SAS, Python, Lua, Java, and REST) in the same place using SAS® Cloud Base Analytics Services (CAS) in SAS Viya. But before you can do any analysis in CAS you need some data to work with, and a way to get to it. Check out this dynamic data selection tip using SAS Viya and Python.
In their new book, SAS Viya: the R Perspective, Kevin Smith and Xiangxiang Meng provide an overview of using R with the SAS Viya platform. Read on to see how R programmers can use CAS.
In addition to the many CAS actions supplied by SAS, as of SAS® Viya™ 3.4, you can create your own actions using CASL. Learn how in this post.
In SAS Viya 3.4, promotion support has been added for many additional SAS 9.4 resources, making it easier to make the leap to Viya. In this blog, SAS' Gerry Nelson reviews this new functionality.
Data in the cloud makes it easily accessible, and can help businesses run more smoothly. SAS Viya runs its calculations on Cloud Analytics Service (CAS). David Shannon of Amadeus Software spoke at SAS Global Forum 2018 on his paper, Come On, Baby, Light my SAS Viya: Programming for CAS.
See how to sample unstructured (text) data using SAS Viya and CAS actions. This post includes complete code to cluster the text documents via k-means, and treats the cluster memberships as strata for analysis.
To reference CAS tables using a one-level name we will issue two statements that alter which libref houses the tables referenced as one-level names.
Cloud Analytic Services (CAS) is really exciting. It’s open, multi-threaded and distributed. And, best of all for SAS programmers, it’s SAS. You can even run DATA Step in CAS. Here's more on how DATA Step work in a multi-threaded, distributed context.

The release of SAS Viya 3.3 has brought some nice data quality features. In addition to the visual applications like Data Studio or Data Explorer that are part of the Data Preparation offering, one can leverage data quality capabilities from a programming perspective. Here is an overview of SAS Data Quality 3.3 programming capabilities.
You can now enable Kerberos delegation across the SAS Platform, using a single strong authentication mechanism across that single platform. As always with configuring Kerberos authentication the prerequisites, in terms of Service Principal Names, service accounts, delegation settings, and keytabs are important for success.
Learn about the new feature of SAS Viya 3.3 that enables Kerberos delegation throughout the environment. It allows you to have end-user sessions in SAS Cloud Analytics Services that are able to use Kerberos to connect to Secured Hadoop.
With SAS Viya 3.3, a new data transfer mechanism Multi Node Data Transfer has been introduced to transfer data between the data source and the SAS’ Cloud Analytics Services. Learn more about this feature.
The R SWAT package (SAS Wrapper for Analytics Transfer) enables you to upload big data into an in-memory distributed environment to manage data and create predictive models using familiar R syntax. In the SAS Viya Integration with Open Source Languages: R course, you learn the syntax and methodology required to
In this article, I will set out clear principles for how SAS Viya 3.3 will interoperate with Kerberos. My aim is to present some overview concepts for how we can use Kerberos authentication with SAS Viya 3.3. We will look at both SAS Viya 3.3 clients and SAS 9.4M5 clients.
Authorization determines what a user can see and do in an application. An authorization system is used to define access control policies, and those policies are later enforced so that access requests are granted or denied. To secure resources in SAS Viya there are three authorization systems of which you need to be aware. The General
The CAS procedure (PROC CAS) enables us to interact with SAS Cloud Analytic Services (CAS) from the SAS client based on the CASL (the scripting language of CAS) specification. CASL supports a variety of data types including INT, DOUBLE, STRING, TABLE, LIST, BLOB, and others. The result of a CAS
SAS Viya provides a robust, scalable, cloud-ready, distributed runtime engine. This engine is driven by CAS (Cloud Analytic Services), providing fast processing for many data management techniques that run distributive, i.e. using all threads on all defined compute nodes. Note: SAS Viya 3.5+ now supports the data set option APPEND=YES.
Many SAS users have inquired about SAS Cloud Analytic Services’ (CAS) Distributed Network File System (DNFS) of late, so let’s look at it further in this blog post. (Learn more about CAS.) The “NFS” in “DNFS” Let’s start at the beginning. The “NFS” in DNFS stands for “Network File System”
