> Python client uses incorrect default value assignment for method parameters

> Key: RANGER-3129
> URL: https://issues.apache.org/jira/browse/RANGER-3129
> Project: Ranger
> Issue Type: Bug
> Components: Ranger
> Affects Versions: 2.2.0
> Reporter: Madhan Neethiraj
> Assignee: Madhan Neethiraj
> Priority: Major
> Fix For: 3.0.0, 2.2.0

>
> Python client implementation for Ranger assigns an empty list as default
> value to method parameters. This can result in errors if the parameter value
> is updated by the method, due to Python handling of default values - more
> details at
> [https://docs.python.org/3/tutorial/controlflow.html#defining-functions]
> (search for *warning*)*:*
> *Important warning:* The default value is evaluated only once. This makes a
> difference when the default is a mutable object such as a list, dictionary,
> or instances of most classes.
>
> Though the parameter value is not updated in Ranger Python client
> implementation, fixing this will help avoid potential issues later.
