Summary: Ambari Views. CapSch View, config elements for ordering
policies
Key: AMBARI-10871
URL: https://issues.apache.org/jira/browse/AMBARI-10871
Project: Ambari
Issue Type: Improvement
Components: ambari-views
Affects Versions: 2.1.0
Reporter: Erik Bergenholtz
Assignee: Antonenko Alexander
Fix For: 2.1.0
We are adding per-queue Ordering policies and comparator configurations to the
Capacity Scheduler. These will need to be surfaced in Ambari.
Both these configurations need to be surfaced in the Capacity Scheduler View:
(1) Display name in UI: Ordering Policy
YARN config name:
yarn.scheduler.capacity.(STANDARD-QUEUE-SPECIFICATION).ordering-policy
The value will be chosen from a drop down with two possible values:
* default value - "fifo" (sans-quotes),
* alternate value - "fair" (sans-quotes)
Open Q: should also accept a fairly long string value (sufficient for fully
qualified java classnames)
(2) Display name in UI: Enable Size Based Weight Ordering
YARN config name:
yarn.scheduler.capacity.(STANDARD-QUEUE-SPECIFICATION).ordering-policy.fair.enable-size-based-weight
The only time this property needs to be set is when (1) is set to 'fair'. When
(1) is set to 'fifo', then this property should not be available in the UI.
The possible values are:
* default value - "false" (sans-quotes)
* alternate value "true" (sans-quotes)
