--------------------------------------------

             Summary: Oozie Hive actions fail when Atlas is installed since Atlas Hive Hooks
need to be copied to Oozie Share Lib in HDFS
                 Key: AMBARI-18151
                 URL: https://issues.apache.org/jira/browse/AMBARI-18151
             Project: Ambari
          Issue Type: Bug
          Components: stacks
    Affects Versions: 2.4.0
            Reporter: Alejandro Fernandez
            Assignee: Alejandro Fernandez
             Fix For: 2.4.0


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

startup.properties
{noformat}
*.application.services=org.apache.falcon.security.AuthenticationInitializationService,\
      org.apache.falcon.workflow.WorkflowJobEndNotificationService, \
      org.apache.falcon.service.ProcessSubscriberService,\

falcon-env.sh
{noformat}
# 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}
{noformat} 

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_$timetamp/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
