Tao Yang updated YARN-8127:
---------------------------
Attachment: YARN-8127.004.patch
> Resource leak when async scheduling is enabled
> ----------------------------------------------
>
> Key: YARN-8127
> URL: https://issues.apache.org/jira/browse/YARN-8127
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Weiwei Yang
> Assignee: Tao Yang
> Priority: Critical
> Attachments: YARN-8127.001.patch, YARN-8127.002.patch,
> YARN-8127.003.patch, YARN-8127.004.patch
>
>
> Brief steps to reproduce
> # Enable async scheduling, 5 threads
> # Submit a lot of jobs trying to exhaust cluster resource
> # After a while, observed NM allocated resource is more than resource
> requested by allocated containers
> Looks like the commit phase is not sync handling reserved containers, causing
> some proposal incorrectly accepted, subsequently resource was deducted
> multiple times for a container.
