expert with interactive programming access to in-memory data and integrates
seamlessly with Hadoop.
In order to use the
offering, the following must be true:
-
You
are using a distributed SAS LASR Analytic Server only.
-
The SAS LASR Analytic Server
is co-located with SAS High-Performance Deployment of Hadoop
or a commercial Hadoop distribution that has been configured with
the services from SAS High-Performance Deployment of Hadoop. The services enable you to use the
SASHDAT file format for storing tables in
HDFS.
-
SAS/ACCESS Interface to Hadoop
is configured on a client machine that you use for submitting SAS
programs. Be sure to install the SAS Embedded Process on the machines
in the Hadoop cluster. The SAS/ACCESS engine, the embedded process,
and the HDMD procedure enable you to describe your data that is in
Hadoop and access it directly without an intermediate metadata repository
such as Hive.

web-based development application that enables you to write and submit
SAS programs. Make sure that your user ID is configured for passwordless
SSH to the machines the cluster. Also make sure that you have passwordless
