Our kerberos TGT is set to expire every 8 hours. This causes issue when a SAS job is executed from SAS EG or SAS Studio as the kerberos Cache is created only once when the session starts through the objectspawner. however when a code executes against hadoop which runs longer than 8 hours fails.

Company policy prohibits extension of TGT duration beyond 8 hours.

Is there any other mechanism to autorenew the TGT Cache so the SAS/Hadoop code does not fail after 8 hours of execution?

I would also like to mention that creating keytabs for individual user accounts is also prohibited according to company policy
