Hi @Naveenraj Devadoss

I've just done it on HDP 3.1 cluster.

Create a new database on postgres (we use postgres for managment database) for registry :

create database registry;
CREATE USER registry WITH PASSWORD 'registry';
GRANT ALL PRIVILEGES ON DATABASE "registry" to registry;

Download hdf-ambari-mpack-<version>.tar.gz https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.3.0/release-notes/content/hdf_repository_locati... on your admin node in /tmp dir

Install mpack :

ambari-server install-mpack --mpack=/tmp/hdf-ambari-mpack-3.4.0.0-155.tar.gz --verbose

Then go to ambari, indicate the HDF base URL on Stack & Version and just add HDF services (NiFi, NiFi registry, Schema Registry).
