-------------------------------------
Summary: Fail fast when default web app context fails to
initialize due to missing resources
Key: ZEPPELIN-6241
URL: https://issues.apache.org/jira/browse/ZEPPELIN-6241
Project: Zeppelin
Issue Type: Improvement
Components: zeppelin-server
Reporter: Chan Ho Lee
Assignee: Chan Ho Lee
Currently, the server keeps running even when all web app contexts fail to
initialize due to missing files or directories for web resources.
In my opinion, if the web resource path for the *default* web app context does
not exist, it would be better to shut down the server immediately, since the
context initialization will fail anyway. In such cases, other essential
features like REST APIs and WebSocket communication also won’t work properly,
so keeping the server running doesn’t seem meaningful.
That said, the absence of non-default web resources seems generally acceptable,
so I think we should only fail fast when the default web app context is missing
its resources.
