> The job client may acquire a history server token during job submission.  The renewer
is specified in a config value that the user must supply (for new api, a bit different for
old api).  If this value is not the RM's principal, then the RM cannot renew the token and
long running jobs will fail.  Since the token is implicitly acquired for the job, the HS token's
renewer should always be the RM's principal.
