I have the Hortonworks sandbox Version 2.6.5. I've been using Cloudera for sometime and thought I'd move over here. I am trying to create a simple Notebook in Zeppelin, here's what happening - the notebook is getting created, I can see it in the listing, but I am unable to edit/open it. I have tried with either user user - maria_dev and admin but of to no avail. Whenever I try to open the notebook, it pops up a window asking me for credentials, and once I specify the credentials it just displays the same Zeppelin page. Almost like a loop, it doesn't open the notebook. I am not sure where the problem is. My shiro.ini file has the following information: - [users] # List of users with their password allowed to access Zeppelin. # To use a different strategy (LDAP / Database / ...) check the shiro doc at http://shiro.apache.org/configuration.html#Configuration-INI Sections maria_dev = <pwd>, admin admin = <pwd>, admin #user1 = password2, role1, role2 #user2 = password3, role3 #user3 = password4, role2 # Sample LDAP configuration, for user Authentication, currently tested for single Realm [main] .............. shiro.loginUrl = /api/login [urls] # anon means the access is anonymous. # authcBasic means Basic Auth Security # To enfore security, comment the line below and uncomment the next one # /api/version = anon # /** = anon /** = authc I am really clueless as to how to solve this. Any help would be appreciated. ... View more
