Parameters

Parameter	Description
`cluster`	The name of the cluster on which to run the command.
`forcerecallexpiry`	Specifies whether (`true`) or not (`false`) to purge recalled data on the MapR cluster. If the command is run with the value for this set to `true`, the compactor purges recalled data on the MapR cluster whether or not the expiry time for recalled data has been reached. If this is not specified or if the value for this is `false`, the compactor purges stale data on the tier and recalled data on the MapR cluster if the expiry time for recalled data has been reached or has passed. The default value is `false`.
`name`	The name of the volume.
