To
use the SASHDAT engine, the following are required:
-
access
to the machines in the cluster where SAS High-Performance Deployment for Hadoop is
installed and running, or a commercial distribution that is configured
with the services from SAS High-Performance Deployment for Hadoop, or the machines
use NFS to mount a distributed file system
-
an operating system user ID that
is configured for passwordless secure shell (SSH) on the machines
in the cluster
The requirement for passwordless SSH is not unique to using
the engine. Passwordless SSH is used throughout SAS High-Performance
Analytics. The SAS High-Performance Computing Management Console can be used to simplify
configuring users for passwordless SSH.
