Alejandro Abdelnur commented on YARN-279:
-----------------------------------------
bq. how would you determine upon submission if the tokens will be valid until
the AM is launched?
Well, reasonable time (that is the point of the 6 months), if they are not
valid when the AM starts, AM should fail.
Bq. Snappy back,....
Agree that we should have a single piece of code to handle all tokens logic.
And it should be in commons for all to use.

> Key: YARN-279
> URL: https://issues.apache.org/jira/browse/YARN-279
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Affects Versions: 3.0.0, 2.0.0-alpha, 0.23.5
> Reporter: Daryn Sharp
>
> Token renewal/cancelation in the RM presents challenges to support arbitrary
> tokens. The RM's CLASSPATH is currently required to have token renewer
> classes and all associated classes for the project's client. The logistics
> of having installs on the RM of all hadoop projects that submit jobs - just
> to support client connections to renew/cancel tokens - are untenable.
