@Allen Niu Starting from Ambari 2.5 you can deploy HDF services on HDP cluster : https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.0.1.1/bk_planning-your-deployment/content/ch_deployment-scenarios.html You can add hosts to your HDP cluster and dedicate them to NiFi using HDP Ambari/Ranger to administer/secure the whole. Using a single server for HDF is a bad idea. You loose high availability and load distribution.

@Allen Niu This might be a tad bit late; however if you want your team to be more experienced developers I would certainly shoot for Spark and Hive. Both components have libraries and jars that support one another and the Spark API makes learning how to develop in Java, Scala, and Python super easy. I personally started to learn how to code in C# and translated those skills into Python and Scala for Spark ML Lib, Spark Core, and Spark SQL. Might be a little biased as I am a BIG SPARK junkie 😉 But the ability to clean data with SPARK at scale is ABSOLUTELY brilliant. I know hortonworks has some great development courses for Spark and Hive as well. Here is the link: https://hortonworks.com/services/training/certification/hdp-certified-spark-developer/ What was your final decision?

Unfortunately currently there is no HA feature available for Ambari yet. However you can refer to the following JIRAs where the discussion is going on in this regard: https://issues.apache.org/jira/browse/AMBARI-17126 AND https://issues.apache.org/jira/browse/AMBARI-7896 - Following link also has some good information regarding the same: https://community.hortonworks.com/questions/402/how-to-setup-high-availability-for-ambari-server.html

This question can be ignored. After further reading, i understood this is expected. Ambari keeps the configuration somewhere else (most likely in its own repository and then extract and refresh the .xml during start up. Sound makes sense for the usage of repository).
