Preparing your CDP Private Cloud Base cluster

Before you begin installing NiFi and NiFi Registry, you need to prepare your CDP Private Cloud Base cluster.

Installing the JDK
You should install JDK on each machine on which you will install NiFi, if your version of Cloudera Manager is not already configured with JDK.
Installing and configuring a database for NiFi Registry
If you are installing NiFi Registry, you can install and configure an external MySQL or PostgreSQL database. By default, NiFi Registry is preconfigured to use an embedded H2 database.
Installing Cloudera Manager and a CDP Private Cloud Base cluster
Before installing NiFi and NiFi Registry, you need to install CDP Private Cloud Base with Cloudera Manager and certain Runtime services.
Installing CFM parcel and CSD files
For installing Cloudera Flow Management (CFM), you need to add the CFM parcel to your cluster using Cloudera Manager to make NiFi and NiFi Registry available for installation.. You also need to upload the NiFi and NiFi Registry Custom Service Descriptor (CSD) files to the default CSD directory. Custom Service Descriptor (CSD) files contain configuration information needed to describe and manage a new service.
