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.
- Java 1.8
- Java 1.11
- Download JDK from the appropriate website.
Run the installation command appropriate for your operating system:
yum install java-1.8.0-openjdk-devel
Once you have installed the JDK, ensure that you have the required database installed and set up for NiFi Registry.
