> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Affects Versions: 3.1.0
> Reporter: Juan Rodríguez Hortalá

>
> The DECOMMISSIONING node state is currently used as part of the graceful
> decommissioning mechanism to give time for tasks to complete in a node that
> is scheduled for decommission, and for reducer tasks to read the shuffle
> blocks in that node. Also, YARN effectively blacklists nodes in
> DECOMMISSIONING state by assigning them a capacity of 0, to prevent
> additional containers to be launched in those nodes, so no more shuffle
> blocks are written to the node. This blacklisting is not effective for
> applications like Spark, because a Spark executor running in a YARN container
> will keep receiving more tasks after the corresponding node has been
> blacklisted at the YARN level. We would like to propose a modification of the
> YARN heartbeat mechanism so nodes transitioning to DECOMMISSIONING are added
> to the list of updated nodes returned by the Resource Manager as a response
> to the Application Master heartbeat. This way a Spark application master
> would be able to blacklist a DECOMMISSIONING at the Spark level.
