[jira] [Comment Edited] (YARN-9472) Add multi-thread asynchronous
scheduling to fair scheduler
[ https://issues.apache.org/jira/browse/YARN-9472?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16818695#comment-16818695 ]

Hi, [~zhuqi].
Multi-thread asynchronous scheduling only means support scheduling in multiple threads, scheduling approaches can be classified as node-based and request-based, currently fair scheduler only support node-based and capacity scheduler can support both, global scheduler is request-based and aims for enhancing scheduling performance and considering complex resource placement requirements.
I think your purpose is to support global scheduler including multi-thread asynchronous scheduling, multi-nodes lookup mechanism, placement constraints etc for fair scheduler, Right?
