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
