@Sami Ahmad Instead of left clicking on the link in step three, right click and select "Save Link As..." option to save the xml template so it can be imported in to your NiFi. The dataflow template will show you all the components needed for this workflow. I believe the intent of this tutorial was not to teach users how to use the NiFi UI, but rather how to use a combination of specific NiFi components to build accomplish a particular workflow. Using the NIFi UI dataflow tools you can recreate the workflow as a UI dataflow building exercise. Thanks, Matt

You are looking at the document to setup RM HA manually, which is a very involved process. You want to use the Ambari UI instead to achieve the same goal with much less effort. The following is the instruction on doing it in Ambari. I have done this many time and should not take you more than 10 minutes. After that, you could go back and check all the conf files to understand what has been changed. http://docs.hortonworks.com/HDPDocuments/Ambari-2.2.2.0/bk_Ambari_Users_Guide/content/_resource_manager_high_availability.html
