[GitHub] [pulsar] sijie opened a new issue #7742: Allow function instance configuring a different instance classpath
sijie opened a new issue #7742:
URL: https://github.com/apache/pulsar/issues/7742
*Motivation*
Currently, the function worker is using the function worker's classpath to configure the function instance (runner)'s classpath. So when the broker (function worker) is using an image that is different from the function instance (runner), the classpath will be wrong and the function instance is not able to load the instance classes.
Example error messages:
```
[WARN] /pulsar/conf on functions instance classpath does not exist
[WARN] /pulsar/lib on functions instance classpath does not exist
Using function root classloader: sun.misc.Launcher$AppClassLoader@7852e922
Using function instance classloader: java.net.URLClassLoader@42a57993
