Junping Du commented on YARN-1354:
----------------------------------
bq. It's possible if they explicitly handle it themselves (e.g.: write out
schema versions and switch on it during load), however they don't typically do
that. I agree that YARN-668 is the proper place to discuss how best to migrate
Credentials and Tokens to a more manageable infrastructure for supporting
upgrades.
Agree. We should have built-in mechanism to handle serialize/deserialize across
versions. Let's discussion more on YARN-668.
bq. Therefore I updated the reconnected node path to forward the applications
running on the node and have the RM inform the NM to finish the application if
it is no longer active.
Sounds good. New added code and tests make sense to me.
+1. Will commit it shortly.
