Daryn Sharp commented on YARN-582: ---------------------------------- I've only glanced over the patch, but do these tokens actually need to be handled specially? Is it feasible to handle all tokens in an opaque credentials within the store? I think that may reduce the copy-n-paste code throughout the stores for restoring these tokens. > Restore appToken and clientToken for app attempt after RM restart > ----------------------------------------------------------------- > > Key: YARN-582 > URL: https://issues.apache.org/jira/browse/YARN-582 > Project: Hadoop YARN > Issue Type: Sub-task > Components: resourcemanager > Reporter: Bikas Saha > Assignee: Jian He > Attachments: YARN-582.1.patch > > > These need to be saved and restored on a per app attempt basis.
