---------------------------------------------

Independent discovery :) I started writing up tests for YARN-39 and immediately ran into this. Have a little patch, cleaning it up now. Will upload it soon.

> The NM's token secret manager will reject all container tokens after the secret key is activated which means the NM will not launch _any_ containers including AMs.  The whole yarn cluster becomes inoperable in 1d.
