Summary: YARN theme and 'yarn.nodemanager.resource.cpu-vcores'
calculation updates
Key: AMBARI-11003
URL: https://issues.apache.org/jira/browse/AMBARI-11003
Project: Ambari
Issue Type: Task
Components: contrib
Affects Versions: 2.1.0
Reporter: Srimanth Gunturi
Assignee: Srimanth Gunturi
Fix For: 2.1.0
Attachments: choice1.png
YARNs theme should be updated as shown in attached screenshot.
Also, the calculation for {{yarn.nodemanager.resource.cpu-vcores}} should be
dependent on {{yarn.nodemanager.resource.percentage-physical-cpu-limit}} and
the #-physical-cores on NodeManager.
{noformat}
minimum = 1
maximum = 2 * #-physical-cores
recommended = max(1, floor(#-physical-cores *
yarn.nodemanager.resource.percentage-physical-cpu-limit))
{noformat}
This new value will be the max of {{yarn.scheduler.minimum-allocation-vcores}}
and {{yarn.scheduler.maximum-allocation-vcores}}.
