Thomas Graves commented on YARN-180:
------------------------------------
note that the container token expired causes the AM to fail the launch of the
container with error like:
2012-10-20 10:27:15,702 ERROR [ContainerLauncher #70]
org.apache.hadoop.mapreduce.v2.app.launcher.ContainerLauncherImpl: Container
launch failed for container_1350066773975_81309_01_011780 : RemoteTrace:

> Capacity scheduler - containers that get reserved create container token to
> early
> ---------------------------------------------------------------------------------
>
> Key: YARN-180
> URL: https://issues.apache.org/jira/browse/YARN-180
> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacityscheduler
> Affects Versions: 0.23.3
> Reporter: Thomas Graves
> Assignee: Arun C Murthy
> Priority: Critical
>
> The capacity scheduler has the ability to 'reserve' containers.
> Unfortunately before it decides that it goes to reserved rather then
> assigned, the Container object is created which creates a container token
> that expires in roughly 10 minutes by default.
> This means that by the time the NM frees up enough space on that node for the
> container to move to assigned the container token may have expired.
