Problem Note 55312: Kerberos tokens are not passed to IBM Platform LSF for grid-launched Workspace Servers

DetailsHotfixAboutRate It

In a Kerberos environment, such as when you use SAS/ACCESS® Interface to Hadoop to access Hadoop resources secured with Kerberos authentication, Kerberos authentication tickets need to be passed to the LSF process that starts SAS. When you use SAS Workspace Servers that are launched by a SAS® grid, however, the Kerberos tickets are not passed to the LSF process, and the SAS Workspace Server does not receive the Kerberos ticket. This can cause to problems with file permissions, with access to DBMS servers, and other issues.

Click the Hot Fix tab in this note to access the hot fix for this issue.

Important: In addition to applying the hot fix, you must add the following environment variable into the SAS Object Spawner start-up code. Edit the ObjectSpawner_usermods.sh script and add this code:

export SAS_GRID_USE_KERBEROS=1

Once you have made this modification, you must re-start your SAS object spawner(s) to enable the fix.
