----------------------------------------------
Summary: Error when using `useAuth` as true in the initiation of
Gateway server
Key: ZEPPELIN-4879
URL: https://issues.apache.org/jira/browse/ZEPPELIN-4879
Project: Zeppelin
Issue Type: Bug
Components: python, python-interpreter, zeppelin-interpreter
Environment: Python: 3.6
Os: Ubuntu 20.04
Zeppelin-Python: 0.9.preview1
Zeppelin-Interpreter: 0.9.preview1
py4J: 0.10.7 (I checked it has a builder )
Reporter: Loghi Perinpanayagam
I want to set my Server address. I could not use the previous
version(before/from 0.8.2 does not have an API to set different IP addresses).
The code starts to interpret while setting the property as false for useAuth.
But fails when true( By default useAuth is true).
{code:java}
properties.setProperty("zeppelin.py4j.useAuth","true");
{code}
Checked the error initiated from this line in `PythonUtils.class`
{code:java}
Class clz = Class.forName("py4j.GatewayServer$GatewayServerBuilder", true,
Thread.currentThread().getContextClassLoader());
{code}
{code:java}
