Review request for Ambari, Alejandro Fernandez and Nate Cole.
Bugs: AMBARI-11358
https://issues.apache.org/jira/browse/AMBARI-11358
Repository: ambari
Description
-------
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.
