> YARN-280 introduced fast-fail for job submissions with bad tokens.
> Unfortunately, other stack components like oozie and customers are acquiring
> RM tokens with a hardcoded dummy renewer value. These jobs would fail after
> 24 hours because the RM token couldn't be renewed, but fast-fail is failing
> them immediately. The RM should always be able to renew its own tokens
> submitted with a job. The renewer field may continue to specify an external
> user who can renew.
