Apache NiFi

Apache NiFi is an easy to use, powerful, and reliable system to process and distribute data.

Table of Contents

Features

Apache NiFi was made for dataflow. It supports highly configurable directed graphs of data routing, transformation, and system mediation logic. Some of its key features include:

  • Web-based user interface
    • Seamless experience for design, control, and monitoring
  • Highly configurable
    • Loss tolerant vs guaranteed delivery
    • Low latency vs high throughput
    • Dynamic prioritization
    • Flows can be modified at runtime
    • Back pressure
  • Data Provenance
    • Track dataflow from beginning to end
  • Designed for extension
    • Build your own processors and more
    • Enables rapid development and effective testing
  • Secure
    • SSL, SSH, HTTPS, encrypted content, etc...
    • Pluggable role-based authentication/authorization

Requirements

  • JDK 1.7 or higher
  • Apache Maven 3.0.5 or higher

Getting Started

To build:

  • Execute mvn clean install or for parallel build execute mvn -T 2.0C clean install. On a modest development laptop that is a couple of years old, the latter build takes a bit under ten minutes. After a large amount of output you should eventually see a success message.

      laptop:nifi fhampton$ mvn -T 2.0C clean install
      [INFO] Scanning for projects...
      [INFO] Inspecting build with total of 115 modules...
          ...tens of thousands of lines elided...
      [INFO] ------------------------------------------------------------------------
      [INFO] BUILD SUCCESS
      [INFO] ------------------------------------------------------------------------
      [INFO] Total time: 09:24 min (Wall Clock)
      [INFO] Finished at: 2015-04-30T00:30:36-05:00
      [INFO] Final Memory: 173M/1359M
      [INFO] ------------------------------------------------------------------------
    

To deploy:

  • Change directory to 'nifi-assembly'. In the target directory, there should be a build of nifi.

      laptop:nifi fhampton$ cd nifi-assembly
      laptop:nifi-assembly fhampton$ ls -lhd target/nifi*
      drwxr-xr-x  3 fhampton  staff   102B Apr 30 00:29 target/nifi-0.1.0-incubating-SNAPSHOT-bin
      -rw-r--r--  1 fhampton  staff   144M Apr 30 00:30 target/nifi-0.1.0-incubating-SNAPSHOT-bin.tar.gz
      -rw-r--r--  1 fhampton  staff   144M Apr 30 00:30 target/nifi-0.1.0-incubating-SNAPSHOT-bin.zip
    
  • For testing ongoing development you could use the already unpacked build present in the directory named "nifi-version-bin", where version is the current project version. To deploy in another location make use of either the tarball or zipfile and unpack them wherever you like. The distribution will be within a common parent directory named for the version.

      laptop:nifi-assembly fhampton$ mkdir ~/example-nifi-deploy
      laptop:nifi-assembly fhampton$ tar xzf target/nifi-*-bin.tar.gz -C ~/example-nifi-deploy
      laptop:nifi-assembly fhampton$ ls -lh ~/example-nifi-deploy/
      total 0
      drwxr-xr-x  10 fhampton  staff   340B Apr 30 01:06 nifi-0.1.0-incubating-SNAPSHOT
    

To run NiFi:

  • Change directory to the location where you installed NiFi and run it.

      laptop:~ fhampton$ cd ~/example-nifi-deploy/nifi-*
      laptop:nifi-0.1.0-incubating-SNAPSHOT fhampton$ ./bin/nifi.sh start
    
  • Direct your browser to http://localhost:8080/nifi/ and you should see a screen like this screenshot: image of a NiFi dataflow canvas

  • For help building your first data flow see the NiFi User Guide

  • If you are testing ongoing development, you will likely want to stop your instance.

      laptop:~ fhampton$ cd ~/example-nifi-deploy/nifi-*
      laptop:nifi-0.1.0-incubating-SNAPSHOT fhampton$ ./bin/nifi.sh stop

Disclaimer

Apache NiFi is an effort undergoing incubation at the Apache Software Foundation (ASF), sponsored by the Apache Incubator PMC.

Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects.

While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

Export Control

This distribution includes cryptographic software. The country in which you currently reside may have restrictions on the import, possession, use, and/or re-export to another country, of encryption software. BEFORE using any encryption software, please check your country's laws, regulations and policies concerning the import, possession, or use, and re-export of encryption software, to see if this is permitted. See http://www.wassenaar.org/ for more information.

The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS), has classified this software as Export Commodity Control Number (ECCN) 5D002.C.1, which includes information security software using or performing cryptographic functions with asymmetric algorithms. The form and manner of this Apache Software Foundation distribution makes it eligible for export under the License Exception ENC Technology Software Unrestricted (TSU) exception (see the BIS Export Administration Regulations, Section 740.13) for both object code and source code.

The following provides more details on the included cryptographic software:

Apache NiFi uses BouncyCastle, Jasypt, JCraft Inc., and the built-in java cryptography libraries for SSL, SSH, and the protection of sensitive configuration parameters. See http://bouncycastle.org/about.html http://www.jasypt.org/faq.html http://jcraft.com/c-info.html http://www.oracle.com/us/products/export/export-regulations-345813.html for more details on each of these libraries cryptography features.
