MetadataMappingService is required for lineage:
{code}
*.application.services=org.apache.falcon.security.AuthenticationInitializationService,\
org.apache.falcon.workflow.WorkflowJobEndNotificationService,\
org.apache.falcon.service.ProcessSubscriberService,\
org.apache.falcon.entity.store.ConfigurationStore,\
org.apache.falcon.rerun.service.RetryService,\
org.apache.falcon.rerun.service.LateRunService,\
org.apache.falcon.service.LogCleanupService,\
org.apache.falcon.metadata.MetadataMappingService
{code}

######### Graph Database Properties #########
# Graph implementation
*.falcon.graph.blueprints.graph=com.thinkaurelius.titan.core.TitanFactory
# Graph Storage
*.falcon.graph.storage.directory=/grid/0/data/lineage/graphdb
*.falcon.graph.storage.backend=berkeleyje
*.falcon.graph.serialize.path=/grid/0/data/lineage
*.falcon.graph.preserve.history=false
{code}
The properties that need a directory in the local file system should detect a mount point that is available on the Falcon server, and the python scripts need to crease these directories when the Falcon service is configured.
The folder permission are,
owner:falcon user
group:hadoop
permissions:775
