**Note:** This feature is in alpha phase and is subject to change.
| Property | Description |
|:---- |:---- |
| `yarn.scheduler.configuration.store.class` | The type of backing store to use, as described [above](CapacityScheduler.html#Changing_Queue_Configuration). |
| `yarn.scheduler.configuration.mutation.acl-policy.class` | An ACL policy can be configured to restrict which users can modify which queues. Default value is *org.apache.hadoop.yarn.server.resourcemanager.scheduler.DefaultConfigurationMutationACLPolicy*, which only allows YARN admins to make any configuration modifications. Another value is *org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.conf.QueueAdminConfigurationMutationACLPolicy*, which only allows queue modifications if the caller is an admin of the queue. |
| `yarn.scheduler.configuration.store.max-logs` | Configuration changes are audit logged in the backing store, if using leveldb or zookeeper. This configuration controls the maximum number of audit logs to store, dropping the oldest logs when exceeded. Default is 1000. |
| `yarn.scheduler.configuration.leveldb-store.path` | The storage path of the configuration store when using leveldb. Default value is *${hadoop.tmp.dir}/yarn/system/confstore*. |
| `yarn.scheduler.configuration.leveldb-store.compaction-interval-secs` | The interval for compacting the configuration store in seconds, when using leveldb. Default value is 86400, or one day. |
| `yarn.scheduler.configuration.zk-store.parent-path` | The zookeeper root node path for configuration store related information, when using zookeeper. Default value is */confstore*. |

**Note:** When enabling scheduler configuration mutations via `yarn.scheduler.configuration.store.class`, *yarn rmadmin -refreshQueues* will be disabled, i.e. it will no longer be possible to update configuration via file.
