> Add property
> yarn.resourcemanager.decommissioning-nodes-watcher.wait-for-applications.
> If true (the default), the resource manager waits for all containers, as well
> as all applications associated with those containers, to finish before
> gracefully decommissioning a node.
> If false, the resource manager only waits for containers, but not
> applications, to finish. For map-only jobs or other jobs in which mappers do
> not need to serve shuffle data, this allows nodes to be decommissioned as
> soon as their containers are finished as opposed to when the job is done.
> Add property
> yarn.resourcemanager.decommissioning-nodes-watcher.wait-for-app-masters.
> If false, during graceful decommission, when the resource manager waits for
> all containers on a node to finish, it will not wait for app master
> containers to finish. Defaults to true. This property should only be set to
> false if app master failure is recoverable.
