| Property | Description |
|:---- |:---- |
| `yarn.scheduler.capacity.per-node-heartbeat.multiple-assignments-enabled` | Whether to allow multiple container assignments in one NodeManager heartbeat. Defaults to true. |
-| `yarn.scheduler.capacity.per-node-heartbeat.maximum-container-assignments` | If `multiple-assignments-enabled` is true, the maximum amount of containers that can be assigned in one NodeManager heartbeat. Defaults to -1, which sets no limit. |
+| `yarn.scheduler.capacity.per-node-heartbeat.maximum-container-assignments` | If `multiple-assignments-enabled` is true, the maximum amount of containers that can be assigned in one NodeManager heartbeat. Default value is 100, which limits the maximum number of container assignments per heartbeat to 100. Set this value to -1 will disable this limit. |
| `yarn.scheduler.capacity.per-node-heartbeat.maximum-offswitch-assignments` | If `multiple-assignments-enabled` is true, the maximum amount of off-switch containers that can be assigned in one NodeManager heartbeat. Defaults to 1, which represents only one off-switch allocation allowed in one heartbeat. |
