It seems like the issue is not completely fixed. It works the first time
when the extensions are deployed for the first time. However upon subsequent
restarts the python processors go into invalid state. When I check the log it
seems like its looking for the bin folder again:

If I change the Scripts folder name to bin and restart again its works and
invalid state goes away!!! Come on guys you cant stop the testing the first
time it runs :)
Also Im not sure why the phython.log file is gone and now all the error are
being logged in to the main nifi-app.log. I think having them separated was
better and easier to find python errors instead of getting buried in the
nifi-app.log.
