> If a user starts a long-running HFTP client using a keytab, we should do
> relogin automatically whenever TGT expires. Currently, HFTP client uses TGT
> to fetch a delegation token and cache that delegation token for HFTP
> operations. The delegation token is automatically renewed/refetched using
> TGT. However, when TGT expires, delegation token renewal/refetch will fail
> and no further HFTP operation is possible. This is unsatisfactory since the
> user has given us her keytab. We should be able to relogin from keytab and
> continue.
