      Description

      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.
