Hi @cestella , thanks for taking a look. The Zeppelin auth credentials are
not related to ambari credentials. They are as defined in
`/etc/zeppelin/conf/shiro.ini` on the Zeppelin host, which is set up by default
during stack deploy time.
Here's a snippet:
```
[root@hcpca-1 ~]# cat /etc/zeppelin/conf/shiro.ini
[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
admin = admin, admin
<snip>
```
When I created the pull request, I considered the option of reading
`shiro.ini` file and parsing for the credentials. I did not pursue that further
since I wanted to address the immediate need of ability to import notebook on
an out-of-the-box Metron cluster. I understand that a thorough way would be to
handle the [different INI
settings](http://shiro.apache.org/configuration.html#Configuration-INISections)
provided by shiro, and could potentially be the scope of another pull request.
Please let me know if it makes sense.
> Zeppelin notebook import does not work with Ambari 2.6

> Key: METRON-1389
> URL: https://issues.apache.org/jira/browse/METRON-1389
> Project: Metron
> Issue Type: Bug
> Affects Versions: 0.4.2
> Reporter: Anand Subramanian
> Assignee: Anand Subramanian
> Fix For: Next + 1
>
>
> This issue is seen with Ambari 2.6.0.0.
> Doing 'Metron -> Service Actions -> Zeppelin Notebook Import' shows that the
> notebooks have been imported, but when I go to the Zeppelin dashboard, I
> cannot find any of the notebooks.
> In recent versions of Ambari, [Shiro
> Authentication|https://zeppelin.apache.org/docs/0.6.0/security/shiroauthentication.html]
> is enabled which requires a user/password authentication in order to
> interact with Zeppelin. We need to incorporate this in order to be able to
> import metron Zeppelin notebooks.
