## 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
|
|
|
|
- Read through the [quickstart guide for development](http://nifi.incubator.apache.org/quickstart.html).
|
|
It will include information on getting a local copy of the source, give pointers on issue
|
|
tracking, and provide some warnings about common problems with development environments.
|
|
- For a more comprehensive guide to development and information about contributing to the project
|
|
read through the [NiFi Developer's Guide](http://nifi.incubator.apache.org/developer-guide.html).
|
|
|
|
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.
|
|
|
|

|
|
|
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-SNAPSHOT-bin
|
|
-rw-r--r-- 1 fhampton staff 144M Apr 30 00:30 target/nifi-0.1.0-SNAPSHOT-bin.tar.gz
|
|
-rw-r--r-- 1 fhampton staff 144M Apr 30 00:30 target/nifi-0.1.0-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-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-SNAPSHOT fhampton$ ./bin/nifi.sh start
|
|
|
|
- Direct your browser to http://localhost:8080/nifi/ and you should see a screen like this screenshot:
|
|
|
|
|
|
- For help building your first data flow see the [NiFi User Guide](http://nifi.apache.org/docs/nifi-docs/user-guide.html)
|
|
|
|
- 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-SNAPSHOT fhampton$ ./bin/nifi.sh stop
|
|

## 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
|
|
