Installing the JDK

You should install JAVA Development Kit (JDK) on each machine on which you will install NiFi, if your version of Cloudera Manager is not already configured with JDK.

  1. Download JDK from the appropriate website.

    For the list of supported JDKs, see System requirements.

  2. Run the installation command appropriate for your operating system:

    For RHEL/CentOS:

    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.
