Daryn Sharp updated MAPREDUCE-4921:
-----------------------------------
Attachment: MAPREDUCE-4921.branch-23.patch
Job submission calls a private method to get the HS token. Proposed change to
always use the RM principal instead of the renewer of the RM token. The HS
token appears to be intended for internal use (since it was implicitly
submitted with the job) so it seems reasonable to always obtain & submit a
token that can be renewed.
Internally tested, will try to write tests and submit patch if this approach is
agreeable.
> JobClient should acquire HS token with RM principal

> 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.
