Zeppelin View is removed from ambari 2.5 but looks like a reference stays there.

So please check if the "resource_id = 58" is pointing to Zeppelin View? You can do this by running the following query on ambari DB.

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:

DELETE FROM adminprivilege where resource_id in (58);
DELETE FROM adminresource where resource_id in (58);

Then restart Ambari Server

# ambari-server stop
# ambari-server start

.

Do you also see a NullPointerException something like following in your ambari server log?

java.lang.NullPointerException
	at org.apache.ambari.server.security.authorization.PermissionHelper.getPermissionLabels

.

Can you please share the complete stackTrace in that case?

@Jay SenSharma

Yes, I can see some Exceptions are like this,

18 May 2017 07:56:33,754 WARN [ambari-client-thread-26] PermissionHelper:78 - Error occurred when cluster or view is searched based on resource id

java.lang.NullPointerException

at org.apache.ambari.server.security.authorization.PermissionHelper.getPermissionLabels(PermissionHelper.java:74)

I guess it is the same Exception you said.

resource_id in(58);

I am using postgresql as embedded DB for ambari. Which database should I use for query. Is it ambari or postgres, please suggest.

@nshelke

If you are using embedded postgres DB the you should try:

# 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.

# grep 'server.jdbc.user.passwd' /etc/ambari-server/conf/ambari.properties 
server.jdbc.user.passwd=/etc/ambari-server/conf/password.dat

# cat /etc/ambari-server/conf/password.dat
bigdata

Were you able to run the select query to findout the problematic resource?

select*from adminresourcetype where resource_type_id IN (select resource_type_id from adminresource where resource_id =58);
