• Configurable prioritization for throughput and latency
• Guaranteed delivery with retry and backoff strategies
• Horizontal scaling with clustering
• Provenance Tracking
• Searchable history with configurable attributes
• Graph data lineage from source to destination
• Metadata and content for each processing decision
• Extensible Design
• Plugin interface for Processors and Controller Services
• Support for Processors in native Python
• REST API for orchestration and monitoring
• Secure Configuration
• Single sign-on with OpenID Connect or SAML 2
• Flexible authorization policies for role-based access
• Encrypted communication with TLS and SFTP

Requirements

NiFi supports modern operating systems and requires recent language versions for developing and running the application.

Platform Requirements

• Java 21

Optional Dependencies

• Python 3.10 or higher

Projects

The source repository includes several component projects.

Please review individual project documentation for additional details.

• Apache NiFi
• Apache NiFi Registry
• Apache NiFi MiNiFi

Getting Started

Project guides provide extensive documentation for installing and extending the application.

• Getting Started
• User Guide
• Administrator Guide
• Developer Guide

Developing

NiFi uses the Maven Wrapper for project development. The Maven Wrapper provides

shell scripts that download and cache a selected version of Apache Maven for running build

commands.

Developing on Microsoft Windows requires using mvnw.cmd instead of mvnw to run Maven commands.

Building

Run the following command to build project modules using parallel execution:

./mvnw install -T1C

Run the following command to build project modules using parallel execution with static analysis to confirm compliance

with code and licensing requirements:

./mvnw install -T1C -P contrib-check

Run the following command to build the application binaries without building other optional modules:

./mvnw install -T1C -am -pl :nifi-assembly

Binaries

The nifi-assembly module contains the binary distribution.

ls nifi-assembly/target/nifi-*-bin.zip

The nifi-assembly module includes the binary distribution in a directory for local development and testing.

cd nifi-assembly/target/nifi-*-bin/nifi-*/

Running

NiFi provides shell scripts for starting and stopping the system.

Running on Microsoft Windows requires using nifi.cmd instead of nifi.sh for system commands.

Starting

Run the following command to start NiFi from the distribution directory:

./bin/nifi.sh start

Accessing

The default configuration generates a random username and password on startup. NiFi writes the generated credentials

to the application log located in logs/nifi-app.log under the NiFi installation directory.

The following command can be used to find the generated credentials on operating systems with grep installed:

grep Generated logs/nifi-app*log

NiFi logs the generated credentials as follows:

Generated Username [USERNAME]
Generated Password [PASSWORD]

The USERNAME will be a random UUID composed of 36 characters. The PASSWORD will be a random string.

The username and password can be replaced with custom credentials using the following command:

./bin/nifi.sh set-single-user-credentials <username> <password>

NiFi defaults to running on the localhost address with HTTPS on port 8443 at the following URL:

https://localhost:8443/nifi

Browsers will display a warning message indicating a potential security risk due to the self-signed certificate

generated during initialization. Production deployments should provision a certificate from a trusted certificate

authority and update the NiFi keystore and truststore configuration.
