      Description

      After the Falcon-Atlas hook has been enabled, the following properties are added.

      startup.properties

      *.application.services=org.apache.falcon.security.AuthenticationInitializationService,\
            org.apache.falcon.workflow.WorkflowJobEndNotificationService, \
            org.apache.falcon.service.ProcessSubscriberService,\
            org.apache.falcon.extensions.ExtensionService,\
            org.apache.falcon.service.LifecyclePolicyMap,\
            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,\
      org.apache.atlas.falcon.service.AtlasService
      

      falcon-env.sh

      # Add the Atlas Falcon hook to the Falcon classpath
      export FALCON_EXTRA_CLASS_PATH=/usr/hdp/current/atlas-client/hook/falcon/*:${FALCON_EXTRA_CLASS_PATH}
      

      Whenever Oozie submits Hive actions, they fail and the application logs show

      This is because whenever Atlas is installed, the Hive Hook (which is installed via the Oozie RPM too, in /usr/$stack/$version/atlas/hook/hive/) needs to be copied to the Oozie Share lib in HDFS (e.g., hdfs:///user/oozie/share/lib/lib_$timestamp/hive)

      Further, need to save atlas-application.properties used for Hive in /etc/oozie/conf/action-conf/hive

      Lastly, remove the atlas.rest.address property from hive-site.xml
