Review System Requirements

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

System requirements for deployments on CDP Private Cloud Base

Supported JDKs:
- Oracle JDK 1.8
- OpenJDK 1.8
- OpenJDK 11
- Azul Zulu JDK 1.8
- Azul Zulu JDK 11
note
JDK limitations and requirements:
- Azul Zulu JDK 1.8 and 11 are only supported when NiFi is installed as a standalone component, not managed by Cloudera Manager, and not part of a CDP cluster.
- If you are using JDK 11, Java 11.0.8 or later is required.
- If you are using Java 8, do not use JDK 8u271, JDK 8u281, and JDK 8u291 as they might cause socket leak issues in NiFi due to JDK-8245417 and JDK-8256818. Consider using a more recent version of the JDK like 8u282, or builds of the JDK where the issue is fixed as described in JDK-8256818.
ZooKeeper – You must install the ZooKeeper service available with your CDP Private Cloud Base cluster.
CFM 2.1.1 supports CDP Private Cloud Base 7.1.6, 7.1.7, 7.1.7 SP1, and 7.1.7 SP2.
4 cores per NiFi node is the minimum number of cores required by Cloudera to be supported. Cloudera recommends 8 cores per NiFi node as it usually provides the best starting point for the most common use cases.
