Resolution: Duplicate
Fixed by MAPREDUCE-5199.
> Cleanup task tokens interface
> -----------------------------
>
> Key: MAPREDUCE-4069
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4069
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: mrv2
> Affects Versions: 0.23.2
> Reporter: Jason Lowe
> Priority: Minor
>
> This tracks a couple of cleanup issues that were identified in MAPREDUCE-4043:
> * It seems unnecessary to pass the job token and credentials separately when
> we always combine the job token into the credentials before building the
> container launch context. The TaskImpl and TaskAttemptImpl constructors
> could simply take credentials with the job token already added rather than
> separate job token and credential parameters.
> * It's unclear whether we still need the appTokens file that is placed into
> HDFS by the job submitter, localized by the NM, and finally read in by the
> AM. I believe the AM's credentials sent in the AM's container launch context
> already contains the same information. If that's the case, we should remove
> the code related to the appTokens file.
