---------------------------------------
Summary: Change Zeppelin REST API Error Code
Key: ZEPPELIN-597
URL: https://issues.apache.org/jira/browse/ZEPPELIN-597
Project: Zeppelin
Issue Type: Improvement
Reporter: CORNEAU Damien
Fix For: 0.5.6
While reviewing a PR, I realized that no REST API call actually have a proper
Error Code.
As stated in the documentation:
https://zeppelin.incubator.apache.org/docs/0.6.0-incubating-SNAPSHOT/rest-api/rest-notebook.html
The only Error code is: 500
However 500 means Internal Error (cf.
https://www.w3.org/Protocols/HTTP/HTRESP.html)
We should provide proper Error code and response message in the REST API, so
that the user can directly be aware of what is wrong.
The current code suggest that Zeppelin crashed, even if the user specified a
wrong parameter.
