> FSNamesystem.dtSecretManager is initialized in FSNamesystem.initialize(), but not started
until activate(). In FSN.stop() it calls dtSecretManager.stopThreads so long as it's non-null,
but doesn't check that the threads have started (ie activate() may never have been called).
This causes an NPE in stopThreads()
> To fix this, stopThreads should check tokenRemoverThread against null before interrupting
it.
