The passive NameNode can be used in high availability configurations, to prevent single point of failure: https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.4/bk_hadoop-high-availability/content/ch_HA-NameNode.html.

Are there any error messages in your log files? Also, in the meantime, you might verify that you have a JDBC driver in /user/oozie/share/lib/lib_<timestamp>/sqoop.

@Lucky_Luke Falcon on HDP 2.5.0 does support Spark actions. See the Data Movement & Integration guide for info. However, Falcon has been deprecated in HDP 2.6 and will be removed in HDP 3.0.

@Saumidh Mhatre And FYI, most actions are asynchronous, so one has to end before the next begins, which you mention you want to happen. For a list of some of the actions available and which are synchronous vs asynchronous, see the Workflow Action Types table in the Workflow Management (WFM) guide (the table applies even if you aren't using WFM, as WFM is based on Oozie).

A couple of things you might try: * Set oozie.use.system.libpath=true in the job.properties file and ensure you have the proper jars in sharelib. * Add the Hive settings file to the workflow.xml, such as <job-xml>hive-site.xml</job-xml>.

Also, the documentation for Workflow Manager is available at http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.0/bk_workflow-management/content/ch_wfm_basics.html. It's available as an Ambari View in HDP 2.6.

The Data Movement and Integration guide might answer some of your questions. In particular, Chapter 5 "Considerations for Using Falcon" and the Important Considerations in Chapter 10, "Mirroring Data with HiveDR in a Secure Environment".

You might check the Data Movement and Integration guide to see if it helps. In particular, chapter 7 "Creating Falcon Entity Definitions".

Currently, you can only deploy HDP components, including Sqoop and Flume, on HDP.
