-## Features
-
-Apache NiFi supports powerful and scalable directed graphs of data routing, transformation, and system mediation logic. Some of the high-level capabilities and objectives of Apache NiFi include:
-
-- Web-based user interface for seamless experience between design, control, feedback, and monitoring of data flows
-- Highly configurable along several dimensions of quality of service such as loss tolerant versus guaranteed delivery, low latency versus high throughput, and priority based queuing
-- Fine-grained data provenance for all data received, forked, joined, cloned, modified, sent, and ultimately dropped as data reaches its configured end-state
-- Component-based extension model along well defined interfaces enabling rapid development and effective testing

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      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
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

-/**
- * <!-- Processor Documentation ================================================== -->
- * <h2>Description:</h2>
- * <p>
- * This processor provides the capability to execute scripts in various
- * scripting languages, and passes into the scripts the input stream and output
- * stream(s) representing an incoming flow file and any created flow files. The
- * processor is designed to be thread safe, so multiple concurrent tasks may
- * execute against a single script. The processor provides a framework which
- * enables script writers to implement 3 different types of scripts:
- * <ul>
- * ReaderScript - which enables stream-based reading of a FlowFile's
- * content</br> WriterScript - which enables stream-based reading and
- * writing/modifying of a FlowFile's content</br> ConverterScript - which
- * enables stream-based reading a FlowFile's content and stream-based writing to
- * newly created FlowFiles</br>
- * </ul>
- * Presently, the processor supports 3 scripting languages: Ruby, Python, and
- * JavaScript. The processor is built on the javax.script API which enables
- * ScriptEngine discovery, thread management, and encapsulates much of the low
- * level bridging-code that enables Java to Script language integration. Thus,
- * it is designed to be easily extended to other scripting languages. </br> The
- * attributes of a FlowFile and properties of the Processor are exposed to the
- * script by either a variable in the base class or a getter method. A script
- * may declare new Processor Properties and different Relationships via
- * overriding the getPropertyDescriptors and getRelationships methods,
- * respectively.
- * </p>
- * <p>
- * <strong>Properties:</strong>
- * </p>
- * <p>
- * In the list below, the names of required properties appear in bold. Any other
- * properties (not in bold) are considered optional. If a property has a default
- * value, it is indicated. If a property supports the use of the NiFi Expression
- * Language (or simply, "expression language"), that is also indicated. Of
- * particular note: This processor allows scripts to define additional Processor
- * properties, which will not be initially visible. Once the processor's
- * configuration is validated, script defined properties will become visible,
- * and may affect the validity of the processor.
- * </p>
- * <ul>
- * <li>
- * <strong>Script File Name</strong>
- * <ul>
- * <li>Script location, can be relative or absolute path.</li>
- * <li>Default value: no default</li>
- * <li>Supports expression language: false</li>
- * </ul>
- * </li>
- * <li>
- * <strong>Script Check Interval</strong>
- * <ul>
- * <li>The time period between checking for updates to a script.</li>
- * <li>Default value: 15 sec</li>
- * <li>Supports expression language: false</li>
- * </ul>
- * </li>
- * </ul>
- *
- * <p>
- * <strong>Relationships:</strong>
- * </p>
- * <p>
- * The initial 'out of the box' relationships are below. Of particular note is
- * the ability of a script to change the set of relationships. However, any
- * relationships defined by the script will not be visible until the processor's
- * configuration has been validated. Once done, new relationships will become
- * visible.
- * </p>
- * <ul>
- * <li>
- * success
- * <ul>
- * <li>Used when a file is successfully processed by a script.</li>
- * </ul>
- * </li>
- * <li>
- * failure
- * <ul>
- * <li>Used when an error occurs while processing a file with a script.</li>
- * </ul>
- * </li>
- * </ul>
- *
- * <p>
- * <strong>Example Scripts:</strong>
- * </p>
- * <ul>
- * JavaScript example - the 'with' statement imports packages defined in the
- * framework. Since the 'instance' variable is intended to be local scope (not
- * global), it must be named 'instance' as it it not passed back to the
- * processor upon script evaluation and must be fetched. If you make it global,
- * you can name it whatever you'd like...but this is intended to be
- * multi-threaded so do so at your own risk. Presently, there are issues with
- * the JavaScript scripting engine that prevent sub-classing the base classes in
- * the Processor's Java framework. So, what is actually happening is an instance
- * of the ReaderScript is created with a provided callback object. When we are
- * able to move to a more competent scripting engine, the code below will remain
- * the same, but the 'instance' variable will actually be a sub-class of
- * ReaderScript.
- *
- * <pre>
- *               with (Scripting) {
- *                 var instance = new ReaderScript({
- *                     route : function(input) {
- *                         var str = IOUtils.toString(input);
- *                         var expr = instance.getProperty("expr");
- *                         filename = instance.attributes.get("filename");
- *                         instance.setAttribute("filename", filename + ".modified");
- *                         if (str.match(expr)) {
- *                             return Script.FAIL_RELATIONSHIP;
- *                         } else {
- *                             return Script.SUCCESS_RELATIONSHIP;
- *                         }
- *                     }
- *                 });
- *               }
- * </pre>
- *
- * Ruby example - the 'OutputStreamHandler' is an interface which is called when
- * creating flow files.
- *
- * <pre>
- *                 java_import 'org.apache.nifi.scripting.OutputStreamHandler'
- *                 class SimpleConverter < ConverterScript
- *                   field_reader :FAIL_RELATIONSHIP, :SUCCESS_RELATIONSHIP, :logger, :attributes
- *
- *                   def convert(input)
- *                     in_io = input.to_io
- *                     createFlowFile("firstLine", FAIL_RELATIONSHIP, OutputStreamHandler.impl do |method, out|

-        <!-- Processor Documentation ================================================== -->
-        <h2>Description:</h2>
-        <p>
-            This processor provides the capability to execute scripts in various scripting languages, and passes into the scripts 
-            the input stream and output stream(s) representing an incoming flow file and any created flow files. The processor is designed to be
-            thread safe, so multiple concurrent tasks may execute against a single script. The processor provides a framework which enables 
-            script writers to implement 3 different types of scripts:
-        <ul>
-            ReaderScript - which enables stream-based reading of a FlowFile's content</br>
-            WriterScript - which enables stream-based reading and writing/modifying of a FlowFile's content</br>
-            ConverterScript - which enables stream-based reading a FlowFile's content and stream-based writing to newly created FlowFiles</br>
-        </ul>
-        Presently, the processor supports 3 scripting languages: Ruby, Python, and JavaScript. The processor is built on the 
-        javax.script API which enables ScriptEngine discovery, thread management, and encapsulates much of the low level bridging-code that 
-        enables Java to Script language integration. Thus, it is designed to be easily extended to other scripting languages. </br>
-        The attributes of a FlowFile and properties of the Processor are exposed to the script by either a variable in the base class or 
-        a getter method. A script may declare new Processor Properties and different Relationships via overriding the getPropertyDescriptors 
-        and getRelationships methods, respectively. 
-    </p>
-    The processor provides some boilerplate script to aid in the creation of the three different types of scripts. For example,
-    the processor provides import statements for classes commonly used within a processor.
-    <pre>
-                'org.apache.nifi.components.PropertyDescriptor'
-                'org.apache.nifi.components.Validator'
-                'org.apache.nifi.processor.util.StandardValidators'
-                'org.apache.nifi.processor.Relationship'
-                'org.apache.nifi.logging.ProcessorLog'
-                'org.apache.nifi.scripting.ReaderScript'
-                'org.apache.nifi.scripting.WriterScript'
-                'org.apache.nifi.scripting.ConverterScript'
-    </pre>
-    The processor appends to the script's execution path the parent directory of the specified script file and a sub-directory
-    called 'lib', which may be useful for supporting scripts. </p>
-<p>
-    <strong>Shared Variables</strong>
-</p>
-The following variables are provided as shared variables for the scripts:
-<ul>
-    <li>logger 
-        <ul>
-            <li> The processor's logger </li>
-            <li> Scope is GLOBAL, thus in Ruby the syntax is $logger</li>
-        </ul>
-    </li>
-    <li>properties
-        <ul>
-            <li> A Map of the processor's configuration properties; key and value are strings</li>
-            <li> Scope is INSTANCE, thus in Ruby the syntax is @properties</li>
-        </ul>
-    </li>
-</ul>
-<p>
-    <strong>Properties:</strong>
-</p>
-<p>
-    In the list below, the names of required properties appear in bold. Any other properties (not in bold) are considered 
-    optional. If a property has a default value, it is indicated. If a property supports the use of the NiFi Expression Language 
-    (or simply, "expression language"), that is also indicated. Of particular note: This processor allows scripts to define additional 
-    Processor properties, which will not be initially visible. Once the processor's configuration is validated, script defined properties
-    will become visible, and may affect the validity of the processor.
-</p>
-<ul>
-    <li>
-        <strong>Script File Name</strong>
-        <ul>
-            <li>Script location, can be relative or absolute path.</li>
-            <li>Default value: no default</li>
-            <li>Supports expression language: false</li>
-        </ul>
-    </li>
-    <li>
-        <strong>Script Check Interval</strong>
-        <ul>
-            <li>The time period between checking for updates to a script.</li>
-            <li>Default value: 15 sec</li>
-            <li>Supports expression language: false</li>
-        </ul>
-    </li>
-</ul>
-
-<p>
-    <strong>Relationships:</strong>
-</p>
-<p>
-    The initial 'out of the box' relationships are below. Of particular note is the ability of a script to change the set of
-    relationships. However, any relationships defined by the script will not be visible until the processor's configuration has been 
-    validated. Once done, new relationships will become visible.
-</p>
-<ul>
-    <li>
-        success
-        <ul>
-            <li>Used when a file is successfully processed by a script.</li>
-        </ul>   
-    </li>
-    <li>
-        failure
-        <ul>
-            <li>Used when an error occurs while processing a file with a script.</li>
-        </ul>   
-    </li>
-</ul>
-
-<p>
-    <strong>Example Scripts:</strong>
-</p>
-<ul>
-    JavaScript example - the 'with' statement imports packages defined in the framework and limits the importing to the local scope, 
-    rather than global. The 'Scripting' variable uses the JavaImporter class within JavaScript. Since the 'instance' variable is intended to 
-    be local scope (not global), it must be named 'instance' as it it not passed back to the processor upon script evaluation and must be 
-    fetched. If you make it global, you can name it whatever you'd like...but this is intended to be multi-threaded so do so at your own 
-    risk.</p>
-Presently, there are issues with the JavaScript scripting engine that prevent sub-classing the base classes in the Processor's Java 
-framework. So, what is actually happening is an instance of the ReaderScript is created with a provided callback object. When we are able
-to move to a more competent scripting engine (supposedly in Java 8), the code below will remain the same, but the 'instance' variable 
-will actually be a sub-class of ReaderScript.
-<pre> 
-              with (Scripting) {
-                var instance = new ReaderScript({
-                    route : function(input) {
-                        var str = IOUtils.toString(input);
-                        var expr = instance.getProperty("expr");
-                        filename = instance.attributes.get("filename");
-                        instance.setAttribute("filename", filename + ".modified");
-                        if (str.match(expr)) {
-                            return Script.FAIL_RELATIONSHIP;
-                        } else {
-                            return Script.SUCCESS_RELATIONSHIP;
-                        }
-                    }
-                });
-              }
-</pre>
-Ruby example - the 'OutputStreamHandler' is an interface which is called when creating flow files.
-<pre>
-                java_import 'org.apache.nifi.scripting.OutputStreamHandler'
-                class SimpleConverter < ConverterScript
-                  field_reader :FAIL_RELATIONSHIP, :SUCCESS_RELATIONSHIP, :logger, :attributes
-                  
-                  def convert(input)
-                    in_io = input.to_io
-                    createFlowFile("firstLine", FAIL_RELATIONSHIP, OutputStreamHandler.impl do |method, out|
-                        out_io = out.to_io
-                        out_io << in_io.readline.to_java_bytes
-                        out_io.close
-                        logger.debug("Wrote data to failure...this message logged with logger from super class")
-                      end)
-                      
-                    createFlowFile("otherLines", SUCCESS_RELATIONSHIP, OutputStreamHandler.impl do |method, out|
-                        out_io = out.to_io
-                        in_io.each_line { |line|
-                          out_io << line
-                        }
-                        out_io.close
-                        logger.debug("Wrote data to success...this message logged with logger from super class")
-                      end)
-                    in_io.close
-                  end
-                   
-                end
-                
-                $logger.debug("Creating SimpleConverter...this message logged with logger from shared variables")
-                SimpleConverter.new
-</pre>
-Python example - The difficulty with Python is that it does not return objects upon script evaluation, so the instance of the Script 
-class must be fetched by name. Thus, you must define a variable called 'instance'.
-<pre>
-                import re
-                
-                class RoutingReader(ReaderScript):
-                    A = Relationship.Builder().name("a").description("some good stuff").build()
-                    B = Relationship.Builder().name("b").description("some other stuff").build()
-                    C = Relationship.Builder().name("c").description("some bad stuff").build()
-                    
-                    def getRelationships(self):
-                        return [self.A,self.B,self.C]
-                  
-                    def getExceptionRoute(self):
-                        return self.C
-                  
-                    def route( self, input ):
-                        logger.info("Executing route")
-                        for line in FileUtil.wrap(input):
-                            if re.match("^bad", line, re.IGNORECASE):
-                                return self.B
-                            if re.match("^sed", line):
-                                raise RuntimeError("That's no good!")
-
