ROOT CAUSE:-
Zeppelin View is removed from ambari 2.5 but looks like a reference stays there.
SOLUTION:-
Check this by running the following query on ambari DB.
# psql -U ambari ambari
Password for user ambari: bigdata
psql => command
-U ambari => is the username
ambari => is the DB name
It will ask for password, Where we can try using the ambari's default password as "bigdata"
If the password is changed then we can check the file.
So please get the "resource_id" of Zeppelin View if present?(In my case it is 58)
# select * from adminresourcetype;
# select * from adminresourcetype; where resource_type_id IN (select resource_type_id from adminresource where resource_id =58);
If that is the case then please Take Ambari DB Dump and then run the following commands to clean the Zeppelin View reference:
# psql -U ambari ambari
Password for user ambari: bigdata
# DELETE FROM adminprivilege where resource_id in(58);
# DELETE FROM adminresource where resource_id in(58);
