> In {{removeApplicationFromRenewal}}, when going to remove a token, and the
> token is shared by other jobs, we will not cancel the token.
> Meanwhile, we should not cancel the _timerTask_, also we should not remove it
> from {{allTokens}}. Otherwise for the existing submitted applications which
> share this token will not get renew any more, and for new submitted
> applications which share this token, the token will be renew immediately.
> For example, we have 3 applications: app1, app2, app3. And they share the
> token1. See following scenario:
> *1).* app1 is submitted firstly, then app2, and then app3. In this case,
> there is only one token renewal timer for token1, and is scheduled when app1
> is submitted
> *2).* app1 is finished, then the renewal timer is cancelled. token1 will not
> be renewed any more, but app2 and app3 still use it, so there is problem.
