candlerb commented on issue #5518: python functions cannot find python3 interpreter

   Hmm, I found [docker/pulsar/scripts/set_python_version.sh](https://github.com/apache/pulsar/blob/master/docker/pulsar/scripts/set_python_version.sh) which suggests that people *are* making python a symlink to python3
   
   ```
   sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 10
   ```
   
   As I say, this is generally frowned upon.
   
   I found there is pythonInstanceLocation in WorkerConfig.java.  The documentation says "change the python instance location only when you put the python instance jar in a different location" - but I'm looking for the python interpreter, not a jar file.  (I don't *think* it's using anything 
   
   I haven't yet found the point where pulsar execs the python interpreter.
