Exactly. If the blob server dies, then the job manager will still shutdown
the cache service though. This is the same behaviour as in the job manager
recovery. Thinking about it, I am wondering myself what we gain by removing the
shutdown hook. In case of hard failures (or kill -9) the shutdown hook is not
called anyways and for all other cases the job manager will shutdown the
components manually anyways. Am I missing something?
