             Summary: During RU, capacity scheduler config needs to be modified for HDP-2.3 to get rid of bad values
                 Key: AMBARI-11358
                 URL: https://issues.apache.org/jira/browse/AMBARI-11358
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.1.0
            Reporter: Jonathan Hurley
            Assignee: Jonathan Hurley
            Priority: Blocker
             Fix For: 2.1.0


The following three config properties should be removed if the values are the HDP-2.2 default.

* yarn.scheduler.capacity.root.accessible-node-labels.default.capacity
** Remove if value is "-1"
* yarn.scheduler.capacity.root.accessible-node-labels.default.maximum-capacity
** Remove if value is "-1"
* yarn.scheduler.capacity.root.default-node-label-expression
** Remove if value is " " (space)

There is currently no logic in place that says remove a property if the property meets a condition. That would require work. Some options:

- We have the ability to set a property if a property meets a condition. For example, we can set {{yarn.scheduler.capacity.root.accessible-node-labels.default.capacity}} to {{""}} or {{10}} if it is currently {{-1}}
- We can just set it regardless of any condition to any value
- We can just remove it outright
- We can write a pre-req check and have the user change it.

The best balance of effort/reward is option #1 - conditionally set the properties.
