You can use Placements Constraints(https://hadoop.apache.org/docs/r3.1.0/hadoop-yarn/hadoop-yarn-site/PlacementConstraints.html) or set yarn.scheduler.capacity.per-node-heartbeat.maximum-container-assignments to 1 if you RM config with capacityscheduler.

For example, let say I have 3 physical nodes. The yarn java application needs 3 containers and each physical node has enough resources to hold 3 yarn containers.
