Summary: Possibly too frequent calls to stack advisor as user
changes sliders
Key: AMBARI-19540
URL: https://issues.apache.org/jira/browse/AMBARI-19540
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 2.5.0
Reporter: Vivek Ratnavel Subramanian
Assignee: Vivek Ratnavel Subramanian
Fix For: 2.5.0
As you can see 3 calls are made while changing from 1024 to 2048 and similarly
3 calls when coming back to 1024.
Beyond performance concern, multiple calls have a functional issue. The call
includes previous value of the changed property - see the values. I would have
expected the old value to be the value that was the original/saved value.
However, it is wherever UI makes the stack advisor calls.
