> This is the counterpart to HADOOP-7967. The token cache currently tries to
> assume a filesystem's token service key. The assumption generally worked
> while there was a one to one mapping of filesystem to token. With the advent
> of multi-token filesystems like viewfs, the token cache will try to use a
> service key (ie. for viewfs) that will never exist (because it really gets
> the mounted fs tokens).
