Also check out info on the standby NameNode: https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.4/bk_hdfs-administration/content/get_ready_to_backup.html

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.

@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).

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.

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

bandalora · ‎05-08-2017

You can find some information in the HDF docs, like this topic on using Sqoop. Also, Flume is deprecated in HDP 2.6 and is being removed in HDP 3.0. See the Release Notes. And here's another topic you might want to check out: HDP and Component Information.

If you are an existing HDP customer, please reach out to your account team and we can share more details.

Did you configure Falcon for HA according to these instructions?

@vsairam, do you know if the original and the secondary errors mentioned above are both still applicable to WFM in Ambari 2.5.0.3 but with HDP 2.6? I'm guessing they are, but want to confirm. Thanks.

@Alex Woolford, Did you configure Kerberos for WFM? http://docs.hortonworks.com/HDPDocuments/Ambari-2.5.0.3/bk_ambari-views/content/wfm-kerberos-setup.html Also, ensure you completed other configuration requirements: http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.0/bk_workflow-management/content/config_wfm_view.html
