Please meet the following
prerequisites before you install and configure the vApp for SAS Data
Loader:
-
Contact your SAS administrator
as needed to confirm that your Hadoop cluster is ready to accept connections
from the vApp for SAS Data Loader. To enable these connections, the
administrator must first install and configure SAS In-Database Technologies
for Hadoop, as described in the
SAS Data Loader for Hadoop: Administrator's Guide.
-
During the configuration process,
you need to identify the location of Hadoop JAR files that are stored
on the client host. Contact your Hadoop administrator to ensure that
the latest Hadoop JAR files have been copied to your computer.
-
To use the directives Copy Data
to Hadoop and Copy Data from Hadoop, you need to copy JDBC drivers
from the Hadoop cluster to the shared folder on your client host,
as directed by your Hadoop administrator. For details,
see Install JDBC Drivers and Add Database Connections in SAS Data Loader for Hadoop: User's Guide. If the SAS Data Loader for Hadoop vApp is already started,
be sure to restart it after you copy the files.
-
If your site uses Kerberos security,
your Hadoop administrator needs to configure Kerberos on the Hadoop
cluster and on your client host, as described in the SAS
Data Loader for Hadoop: Administrator’s Guide.
The Hadoop administrator also needs to provide Kerberos configuration
values and the locations of the Kerberos files that were installed
on your client host. If you do not have this information, contact
your Hadoop administrator.
-
Configure the supported browser
on the client host to support Integrated Windows Authentication (IWA).
This configuration process might have been performed by your Hadoop
administrator. To confirm or add IWA support, see
Support for Integrated Windows Authentication in the
SAS Intelligence Platform: Middle-Tier Administration Guide.
-
If your site intends to use the
directive Load Data to LASR, then your SAS Administrator needs to
install a grid of SAS LASR Analytic Servers, release 6.4 or later.
For more information, including configuration prerequisites,
see Load Data to LASR in SAS Data Loader for Hadoop: User's Guide.
