Review comment:
so just to be clear, these fileystems are ones the user specified in
spark.kerberos.access.hadoopFileSystems so it wants to get initial tokens for
them but then later we don't want to renew, correct? We should perhaps update
doc to mention that.
It would be nice to know if this works with other cluster managers like k8s
- @ifilonenko @mccheah maybe?
