> 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.
