Subject [jira] [Commented] (YARN-9161) Absolute resources of capacity scheduler doesn't support GPU and FPGA
Date Tue, 29 Jan 2019 04:52:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-9161?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16754599#comment-16754599

Zac Zhou commented on YARN-9161:
--------------------------------

YARN-9161.009.patch is to fix some checkstyle and findbugs issues. I run TestCapacitySchedulerMetrics
locally and it succeeded.

[~sunilg], [~leftnoteasy], [~tangzhankun], can you help to review when you are free~

> As the enum CapacitySchedulerConfiguration.AbsoluteResourceType only has two elements:
memory and vcores, which would filter out absolute resources configuration of gpu and fpga in
AbstractCSQueue.updateConfigurableResourceRequirement. 
> This issue would cause gpu and fpga can't be allocated correctly
