[jira] [Commented] (NIFI-210) Provide an ExecuteScript processor

["Matt Burgess (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NIFI-210?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15060406#comment-15060406 ] 

Matt Burgess commented on NIFI-210:
-----------------------------------

Attached new patch to supercede the other, and to offer two processors:

InvokeScriptProcessor: For JSR-223 script engines that are Invocable, the user can provide a scripted Processor implementation, to which the InvokeScriptProcessor will delegate methods such as getRelationships(), onTrigger(), etc.

ExecuteScript: This processor allows the user to provide a script to act as the body of an onTrigger() method. It must return a FlowFile object, which will be routed to success. If the script does not return a FlowFile, the original FlowFile will be routed to "no-flowfile". If any script error occurs, the original FlowFile will be routed to failure.

The current list of supported languages is Javascript (in Java 8), Groovy, JRuby, Jython, Lua, and Scala.
