Robert Joseph Evans commented on MAPREDUCE-4921:
------------------------------------------------

The patch looks fine to me I am +1 for it for trunk and branch-2.  For 
branch-0.23 it looks like the patch no longer applies (TestYARNRunner.java 
appears to have been updated)  Could you upmerge it?

I'll check it in for the others.

> 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.
