Alejandro Abdelnur commented on YARN-1160:
------------------------------------------
You can already ask for container exactly on a specific node setting
relaxLocality to FALSE in the ResourceRequest. Though, this does not allow you
to get a container if there is no capacity in the node.
> allow admins to force app deployment on a specific host

> Key: YARN-1160
> URL: https://issues.apache.org/jira/browse/YARN-1160
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Affects Versions: 3.0.0
> Reporter: Steve Loughran
> Priority: Minor
>
> Currently you ask YARN to get slots on a host and it finds a slot on that
> machine -or, if unavailable or there is no room, on a host nearby as far as
> the topology is concerned.
> People with admin rights should have the option to deploy a process on a
> specific host and have it run there even if there are no free slots -and to
> fail if the machine is not available. This would let you deploy
> admin-specific process across a cluster.
