<description>
The type of configuration store to use for storing scheduler
configurations, if using a mutable configuration provider.
Keywords such as "memory" map to certain configuration store
implementations. If keyword is not found, try to load this
value as a class.
The type of configuration store to use for scheduler configurations.
Default is "file", which uses file based capacity-scheduler.xml to
retrieve and change scheduler configuration. To enable API based
scheduler configuration, use either "memory" (in memory storage, no
persistence across restarts), "leveldb" (leveldb based storage), or
"zk" (zookeeper based storage). API based configuration is only useful
when using a scheduler which supports mutable configuration. Currently
only capacity scheduler supports this.

Changing Queue Configuration
----------------------------
Changing queue/scheduler properties and adding/removing queues can be done in two ways, via file or via API.
Changing queue/scheduler properties and adding/removing queues can be done in two ways, via file or via API. This behavior can be changed via `yarn.scheduler.configuration.store.class` in yarn-site.xml. Possible values are *file*, which allows modifying properties via file; *memory*, which allows modifying properties via API, but does not persist changes across restart; *leveldb*, which allows modifying properties via API and stores changes in leveldb backing store; and *zk*, which allows modifying properties via API and stores changes in zookeeper backing store. The default value is *file*.

Editing by API uses a backing store for the scheduler configuration. To enable this, the following parameters can be configured in yarn-site.xml.
**Note:** This feature is in alpha phase and is subject to change.
| Property | Description |
|:---- |:---- |
| `yarn.scheduler.capacity.configuration.provider` | The type of configuration provider to use for capacity scheduler. To enable changing queue configuration via API, this should be set to *store*. Default value is *file*, which disables the API and reverts back to changing queue configuration via file. |
| `yarn.scheduler.configuration.store.class` | The type of backing store to use. Default value is *memory*, which stores the scheduler configuration in memory (and does not persist configuration changes across restarts). Other values are *leveldb* (using a leveldb-based implementation), and *zk* (using a zookeeper-based implementation). |
| `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 backing store for scheduler configuration, *yarn rmadmin -refreshQueues* will be disabled, i.e. it will no longer be possible to update configuration via file.
**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.
