> 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).
