Vinod Kumar Vavilapalli updated MAPREDUCE-3380:
-----------------------------------------------
Attachment: MAPREDUCE-3380-20120110.1.txt
+1 overall. Cleaned the patch a bit.
- Adding extra check for Kerberos authentication when asking for delegation
tokens
- Reusing the same record DelegationToken for both RM side and JHS side tokens
- Removed unnecessary changes to minimize the patch size and to make it
tractable for review.
- There may be better ways to populate the history related delegation tokens
but the current one to pass around info via conf should do the trick for now.
> Token infrastructure for running clients which are not kerberos authenticated

> The JobClient.getDelegationToken() method is returning NULL, this makes Oozie
> fail when trying to get the delegation token to use it for starting a job.
> What is seems to be happing is that Jobclient.getDelegationToken() calls
> Cluster.getDelegationToken() that calls YarnRunner.getDelegationToken() that
> calls ResourceMgrDelegate.getDelegationToken(). And the last one is not
> implemented. (Thanks Ahmed for tracing this in MR2 code)
