Its a two step process and has to be done from Ambari only. Otherwise the changes will not be retained in shiro.ini and it will get overwritten the moment zapplin service is restarted. Any way here are the steps : from ambari Zeppelin > Configs > Advanced zeppelin-env > shiro_ini_content and change the following : A. [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-INISections maria_dev =<password>, admin #### Add this line #admin = password1, admin #user1 = password2, role1, role2 #user2 = password3, role3 [urls] B. Under URL section make the changes shown below : [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 ## commened this line #/** = anon ##commented this line /** = authc ## uncommented this line Then restart zapplin. try to log in again. This should solve the problem. ... View more

Its a two step process involving changes in 4 lines which i have marked below. Access shiro.ini from Ambari using admin user id only . Please note accessing it any other way will not be useful as it will not preserve the change and will keep getting overwritten every time the zapplin service is restarted. So access shiro.ini in the following path : Ambari, Zeppelin > Configs > Advanced zeppelin-env > shiro_ini_content and make the following changes : A. # 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-INISections maria_dev =<password>, admin #### <------Add this line #this is the first change# #admin = password1, admin B. Near the end of the file there you should file the following lines : # 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 <------comment this line #this is the second change# #/** = anon <------comment this line #this is the third change# /** = authc <------uncomment this line #this is the fourthchange# ...
