Subject [jira] [Commented] (YARN-60) NMs rejects all container tokens after secret key rolls
Date Thu, 30 Aug 2012 16:38:07 GMT

Vinod Kumar Vavilapalli commented on YARN-60:
---------------------------------------------

All the changes in the patch are needed to fix the issue at hand. It will not prevent us from
adding per-node keys in the near future in any ways possible, not sure which code made you
say so.

> 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.
