> NMTokenCache is a singleton. Because of this, if running multiple AMs in a
> single JVM NMTokens for the same node from different AMs step on each other
> and starting containers fail due to mismatch tokens.
> The error observed in the client side is something like:
> {code}
> ERROR org.apache.hadoop.security.UserGroupInformation:
> PriviledgedActionException as:llama (auth:PROXY) via llama (auth:SIMPLE)
> cause:org.apache.hadoop.yarn.exceptions.YarnException: Unauthorized request
> to start container.
> NMToken for application attempt : appattempt_1382038445650_0002_000001 was
> used for starting container with container token issued for application
> attempt : appattempt_1382038445650_0001_000001
> {code}
