+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the
+ Work (including but not limited to damages for loss of goodwill,
+ work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses), even if such Contributor
+ has been advised of the possibility of such damages.
+
+ 9. Accepting Warranty or Additional Liability. While redistributing
+ the Work or Derivative Works thereof, You may choose to offer,
+ and charge a fee for, acceptance of support, warranty, indemnity,
+ or other liability obligations and/or rights consistent with this
+ License. However, in accepting such obligations, You may act only

+## 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.apache.org/quickstart.html).
+- 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.apache.org/developer-guide.html).
-- Optional: Build supporting modules. This should only be needed if the current 'nifi' module is in
- the process of updating to a new version of either the 'nifi-parent' or 'nifi-nar-maven-plugin'
- artifacts.
-
- If in doubt, just skip to building the main nifi project. If the build fails, come back here and
- figure out which optional step you are missing; each entry below will give an example of the
- errors you'll receive if that step needs to be followed. The version numbers may change but the
- error text should still look very familiar.
- - Install the nifi-parent pom. Change directory to 'nifi-parent' and follow the directions found
- there in [README.md](nifi-parent/README.md).
-
- If you don't build the nifi-parent pom and the main nifi code relies on an unreleased version
- you'll see an erorr like the following:
-
- [ERROR] Non-resolvable parent POM: Could not find artifact
- org.apache.nifi:nifi-parent:pom:1.0.0-SNAPSHOT in example.snapshots.repo
- (https://repository.example.com/content/repositories/snapshots) and
- 'parent.relativePath' points at no local POM @ line 18, column 13 -> [Help 2]
- - Build the nifi-nar-maven-plugin. Change directory to 'nifi-nar-maven-plugin' and
- follow the directions found there in [README.md](nifi-nar-maven-plugin/README.md).
-
- If you don't build the nifi-nar-maven-plugin and the main nifi code relies on an unreleased
- version you'll see an error like the following:
-
- [ERROR] Unresolveable build extension: Plugin
- org.apache.nifi:nifi-nar-maven-plugin:1.0.1-SNAPSHOT or one of its
- dependencies could not be resolved: Could not find artifact
- org.apache.nifi:nifi-nar-maven-plugin:jar:1.0.1-SNAPSHOT -> [Help 2]
-- Build nifi. Change directory to 'nifi' and follow the directions found there in
- [README.md](nifi/README.md).
-- Run NiFi. The directions found in the [README.md](nifi/README.md) file within the 'nifi' module
- will also include how to run an instance of NiFi. For help on how to build your first data flow,
- see the [NiFi User Guide](http://nifi.apache.org/docs/nifi-docs/user-guide.html).
+ 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.

+- 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

+/**
+ * <p>
+ * Marker annotation a {@link org.apache.nifi.processor.Processor Processor} or
+ * {@link org.apache.nifi.reporting.ReportingTask ReportingTask} implementation
+ * can use to indicate a method should be called whenever the component is
+ * scheduled to run. This will be called before any call to 'onTrigger' and will
+ * be called once each time a Processor or Reporting Task is scheduled to run.
+ * This occurs in one of two ways: either a user clicks to schedule the
+ * component to run, or NiFi is restarted with the "auto-resume state"
+ * configuration set to true (the default value) and the component is already
+ * running.
+ * </p>
+ *
+ * <p>
+ * Methods using this annotation must take either 0 arguments or a single
+ * argument.
+ * </p>
+ *
+ * <p>
+ * If using 1 argument and the component using the annotation is a Processor,
+ * that argument must be of type
+ * {@link org.apache.nifi.processor.ProcessContext ProcessContext}.
+ * </p>
+ *
+ * <p>
+ * If using 1 argument and the component using the annotation is a Reporting
+ * Task, that argument must be of type
+ * {@link org.apache.nifi.controller.ConfigurationContext ConfigurationContext}.
+ * </p>
+ *
+ * If any method annotated with this annotation throws any Throwable, the
+ * framework will wait a while and then attempt to invoke the method again. This
+ * will continue until the method succeeds, and the component will then be
+ * scheduled to run after this method return successfully.
