Re: accessing zeppelin via knox returns empty page
Also, can you try adding forward slash to your url, i.e.
https://test-namenode.subnet1.hadoop.oraclevcn.com:8443/gateway/ui/zeppelin/
Best,

accessing zeppelin via knox returns empty page
Hi,
I am using HDP2.6, knox, ranger, ldap. I can access zeppelin directly using
admin/admin as username/password. However, accessing zepplin via knox gets
200 status code but empty page.
Using curl, I found the responses (at the end) are the same for:
without knox:
curl -ik -H 'Cache-Control: no-cache' -u admin:"password"
http://test-namenode.subnet1.hadoop.oraclevcn.com:9995
with knox:
curl -ik -H 'Cache-Control: no-cache' -u admin:"password"
https://test-namenode.subnet1.hadoop.oraclevcn.com:8443/gateway/ui/zeppelin
Any idea why the browser does not show the login page? Appreciate any help!
