Major Description
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.
