---------------------------------------
Summary: Fix null pointer exception when the interpreter
repository's url protocol is http
Key: ZEPPELIN-4926
URL: https://issues.apache.org/jira/browse/ZEPPELIN-4926
Project: Zeppelin
Issue Type: Bug
Components: Interpreters
Affects Versions: 0.8.2
Reporter: lee jong hyun
Fix For: 0.9.0
Correct the phenomenon that there couldn't access when the url protocol of
repository is http.
If the repository's url protocol is http, it tries to access the repository
through LightweightHttpWagon.
Inside the LightweightHttpWagon, the authenticator is referenced.
At this time, the authenticator is null referenced, resulting in a null pointer
exception.
Set the LightweightHttpWagonAuthenticator in the part that creates
LightweightHttpWagon to solve the problem.
