> Key: AMBARI-21118
> URL: https://issues.apache.org/jira/browse/AMBARI-21118
> Project: Ambari
> Issue Type: Bug
> Components: stacks
> Affects Versions: 2.5.1
> Reporter: Alejandro Fernandez
> Assignee: Alejandro Fernandez
> Fix For: 2.5.2
>
> Attachments: AMBARI-21118.2.5-maint.patch
>
>
> STR:
> * Install Ambari 2.5.1 with HDP 2.6.1 plus Storm and Streamline (from HDF
> MPack)
> * Attempt to change configs for Storm
> Ambari: 2.5.1.0-146
> HDF: 3.0.0.0-358
> HDP: 2.6.1.0-110
> This is happening because Storm does not have Streamline as a dependent
> service, so the UI does not pass the Streamline configs to the
> recommendations endpoint when calling Stack Advisor for Storm.
