API works in browser but not postman / python
Hi all,
I have been trying to touch Zeppelin by API call.
If I type
https://[cluster name]/zeppelin/api/notebook/
it works, without prompting login page and display resulting JSON in web
page
But if I do same query in postman / python, it just won't work
Could not get any response
There was an error connecting to https://[cluster
name]/zeppelin/api/notebook/
<https://xgjtv7-asw-prod-eu-rg-spark-esp.azurehdinsight.net/zeppelin/api/notebook/>
.
Why this might have happened:
- The server couldn't send a response:
Ensure that the backend is working properly
- Self-signed SSL certificates are being blocked:
Fix this by turning off 'SSL certificate verification' in *Settings >
General*
- Proxy configured incorrectly
Ensure that proxy is configured correctly in *Settings > Proxy*
- Request timeout:
Change request timeout in *Settings > General*
I have disabled SSL certification verification accordingly. No proxy
involved in connection.
Also note that in Chrome Developer Tool it shows a request header as
Cookie, will this one critical to request as well? But based on the error I
have I think it's connection layer rather than authentication layer.
Thanks
