To
use the SASHDAT engine, the following are required:
-
access
to the machines in the cluster where Hadoop is configured with the
SAS Plug-ins for Hadoop, or where 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.
