Need help in enabling Zeppelin-SSO authentication

[Ravikumar, Praveen Krishnamoorthy]

Greetings,

I’m working on enabling knox-sso authentication in Zeppelin. I configured 
Zeppelin UI host in the topology XML , made the configuration changes to enable 
zeppelin in knox ( suggested in the documentation ). Now I’m facing few issues 
on accessing the zeppelin via knox gateway url, which I have detailed below. 
Could anyone please help me in this, would be very helpful to proceed further.

I’m seeing the below log error messages on starting the zeppelin.

Configuration changes:


  1.  Zeppelin : shiro.ini

knoxJwtRealm = org.apache.zeppelin.realm.jwt.KnoxJwtRealm
knoxJwtRealm.providerUrl = 
https://<dns-domain>:8446/<https://%3cdns-domain%3e:8446/>
knoxJwtRealm.login = gateway/knoxsso/api/v1/websso
knoxJwtRealm.logout = gateway/knoxssout/api/v1/webssout
knoxJwtRealm.logoutAPI = true
knoxJwtRealm.redirectParam = originalUrl
knoxJwtRealm.cookieName = hadoop-jwt
knoxJwtRealm.publicKeyPath = /etc/zeppelin/conf/knoxsso.pem
knoxJwtRealm.groupPrincipalMapping = group.principal.mapping
knoxJwtRealm.principalMapping = principal.mapping
authc = org.apache.zeppelin.realm.jwt.KnoxAuthenticationFilter
