David Handermann created NIFI-11630:
---------------------------------------

             Summary: Deprecate ECMAScript and python Script Engines
                 Key: NIFI-11630
                 URL: https://issues.apache.org/jira/browse/NIFI-11630
             Project: Apache NiFi
          Issue Type: Task
          Components: Extensions
            Reporter: David Handermann
            Assignee: David Handermann
             Fix For: 1.latest


The {{ECMAScript}} and {{python}} Script Engines for multiple scripted Processors and Controller Services should be deprecated for removal in NiFi 2.0.

The {{ECMAScript}} engine supports JavaScript-compatible scripted components. The Nashorn engine was deprecated in Java 11 as described in [JEP 335|https://openjdk.org/jeps/335] and is no longer available in Java 17. Alternative JavaScript engines could be considered separately, but {{ECMAScript}} should be deprecated for removal.

The {{python}} engine supports Python-compatible scripted components using [Jython|https://www.jython.org/]. Experimental framework support for native Python Processors is available in the current main branch, which will provide a clear alternative to Jython-based scripting.
