Hi experts, I have a use-case with an external session token that is short lived and does not renew(ie, unlike a hadoop delegation token, the expiry time is not updated for this token). For a long running application (longer than the lifespan of the external token), I want to update the UGI/Credential object of each and every worker container with a new token.
If I understand correctly, all delegation tokens are shared at the launch of a container. Is there any way to update the credential object after the launch of the container and during the lifespan of the application? Best, Ankur Khanna
