[jira] [Commented] (YARN-9047) FairScheduler: default resource
calculator is not resource type aware
[ https://issues.apache.org/jira/browse/YARN-9047?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16783378#comment-16783378 ]

----------------------------------
Hi [~snemeth],
Do you have an update for this?
Also I find it quite strange that {{TestFairScheduler.java}} got so many imports. Check in your next patch whether all of them are necessary.

> The FairScheduler#getResourceCalculator always returns the default resource calculator. The default calculator is not resource type aware and should only be used if there are no resource types configured.
> We need to make sure that in we the direct hard code reference to {{RESOURCE_CALCULATOR}} is either safe to use in all cases or is not used in the scheduler.
