Review System Requirements

Before getting started with the Cloudera Flow Management (CFM) installation, it is helpful to review the system requirements.

System requirements🔗

JDK 8 – If your cluster is already configured with JDK 8, you may skip this step. If not, install JDK 8 before proceeding.

note

If you are using Java 8, do not use JDK 8u271. JDK 8u271 may cause socket leak issues in NiFi due to JDK-8245417.
ZooKeeper – You may add the ZooKeeper service available with your CDH cluster.
CFM supports Cloudera Manager and CDH versions 6.x and 5.5.6 and later. This documentation assumes you already have a CDH cluster installed. If you do not, see the Cloudera Manager installation documentation.
