---------------------------------------
Summary: Investigate and fix the initialization of
ExecutePythonProcessor
Key: MINIFICPP-1355
URL: https://issues.apache.org/jira/browse/MINIFICPP-1355
Project: Apache NiFi MiNiFi C++
Issue Type: Task
Affects Versions: 0.7.0
Reporter: Adam Hunyadi
Fix For: 1.0.0
Attachments: Screenshot 2020-09-04 at 16.02.41.png
*Background:*
Currently, even though the tests for ExecutePythonProcessor are passing, if I
were to try and load up a configuration that contains an
ExecutePythonProcessor, it fails due to trying to load an incorrect script file.
Sample flow:

When trying to check in debugger, it seems like the processors script file is
always replaced with an incorrect one, and the processor fails to start.

This is how it is set:
{code:c++|title=Trace of where the property is overridden}
ConfigurableComponent::setProperty()
std::shared_ptr<core::CoreComponent> create()
ClassLoader::instantiate()
PythonCreator::configure() <- here the first element of classpaths_ is read to
overwrite the config
FlowController::initializeExternalComponents()
{code}
When trying to perform the same thing on the 0.7.0 release version, the startup
already shows some kind of errors, although they seem different:
