[jira] [Commented] (YARN-8590) Fair scheduler promotion does not
update container execution type and token
[ https://issues.apache.org/jira/browse/YARN-8590?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16569376#comment-16569376 ]
Miklos Szegedi commented on YARN-8590:
--------------------------------------
Thank you for the patch [~haibochen].
{code:java}
941 container.setExecutionType(ExecutionType.GUARANTEED);{code}
This code will execute, even if the token update failed. I think this function should be atomic and keep the execution type, if the token generation fails.

> Fair Scheduler promotion of opportunistic containers does not update container execution type and token. This leads to incorrect resource accounting when the promoted containers are released.
