Step 6: Open and Configure SAS Data Loader: Information Center

Open the Information Center

SAS Data Loader: Information Center is a web application that enables you to configure SAS Data Loader for Hadoop, download vApp updates, access product documentation, and start the SAS Data Loader for Hadoop web application.

Follow these steps to open SAS Data Loader: Information Center:

Open VMware Player Pro if it is not already open, and click SAS Data Loader.
When SAS Data Loader appears, click Play virtual machine.
VMware Player Pro requires a minute or two to play the vApp. When the vApp is ready, VMware Player displays the message Welcome to your SAS Data Loader Virtual Application. (If an informational Removable Devices window appears, review the information about removable devices and click OK.)
In the window SAS Data Loader – VMware Player Pro, locate the HTTP address to connect to the SAS Data Loader
Open a supported browser, and enter the HTTP address in the browser’s address bar. Press Enter to open SAS Data Loader: Information Center.

Complete the Basic Configuration

Follow these steps to complete the basic configuration of the SAS Data Loader: Information Center:

The first time you open the Information Center, the Settings window appears. In the SAS Data Loader license field, specify the location of your SAS Data Loader license file. The license filename has the format SAS_vApp_order-number_license.txt. The file is located in the sid_files subdirectory of the software depot where you downloaded the SAS Data Loader software, and it is also attached to your Software Order Email.
Right-click in the Hadoop version field and select a version from the list.
If your site does use Kerberos security, go to Complete Additional Steps for Kerberos.

Note: If you are unsure about the use of Kerberos security at your site, contact your network administrator or Hadoop administrator.

If your site does not use Kerberos security, follow these steps:
1. Make sure that you have not selected Run Data Loader in secure mode.
2. Click OK to save your settings. SAS Data Loader: Information Center proceeds to update configuration files for a minute or two.
3. SAS Data Loader: Information Center displays a message telling you to copy configuration files from the Hadoop cluster to the shared folder. Click Close, and continue to Step 7: Copy Hadoop Configuration Files into the Shared Folder for instructions.

Complete Additional Steps for Kerberos

As one of the prerequisites for installing SAS Data Loader for Hadoop, your Hadoop administrator was asked to provide you with the information that you need to configure Kerberos security. The administrator was also asked to deliver certain files to you or install those files on your client host.

In the Setup window for SAS Data Loader: Information Center, follow these steps to configure Kerberos security on your client host:

Click Run SAS Data Loader in secure mode.

CAUTION:

Do not click “Run Data Loader in secure mode” and click “OK” unless you are certain that you will configure a Hadoop cluster that uses Kerberos authentication.

After you click Run Data Loader in secure mode and click OK, you cannot reconfigure your vApp to connect to an unsecured Hadoop cluster. If you need to configure an unsecured Hadoop cluster at that point, you are required for reasons of security to download a new vApp.
In the Hostname field, enter the name of your client host as it was defined by your Hadoop administrator. This host name is different from your normal network host name.
In the User ID for host login field, enter your normal login ID.
In the Realm for user ID field, enter the Kerberos realm for your host name, as provided by your administrator. The Kerberos realm is similar to a Windows domain.
In the krb5 configuration field, enter the location of your Kerberos configuration file.
In the Host keytab field, enter the location of the host keytab file. The three keytab files authenticate the host, SAS, and the vApp HTTP server to one another and to the Active Directory authentication provider.
In the SAS server keytab field, enter the location of the SAS server keytab file.
In the HTTP keytab field, enter the location of the keytab file of the HTTP server in the vApp for SAS Data Loader.
In the Local JCE security policy jar field, enter the location of this Java archive file. This Java Cryptology Extension defines the implementation of encryption at your site.
In the US JCE security policy jar field, enter the location of the United States JCE JAR file.
Click OK. SAS Data Loader: Information Center proceeds to update configuration files for a minute or two.
SAS Data Loader: Information Center displays a message telling you to copy configuration files from the Hadoop cluster to the shared folder. Click Close, and continue to the next topic for instructions.
