> Currently, {{RemoteWasbAuthorizerImpl.getRelativeBlobSASUri()}}, {{RemoteWasbAuthorizerImpl.getContainerSASUri()}} and {{RemoteSASKeyGeneratorImpl.authorize()}} use Kerberos interactive user's ticket cache if the kerberos credential is not available for {{UserGroupInformation.getCurrentUser()}} or {{UserGroupInformation.getRealUser()}}.
> It results in usage of interactive user's ticket for impersonation, whenever services try to do File System operations as another user, which is incorrect.
