Vinod Kumar Vavilapalli commented on YARN-2152:
-----------------------------------------------
Unfortunately, token versioning is a pending item under YARN-666 (mentioned in
the design discussion and one we are actively thinking about offline).
There is no way to handle it today. The story I have in mind is that once we
have versioned-token-handling in place, we can safely add new fields. Till
then, we will see container failures during upgrades whenever we add fields.
> Recover missing container information
